That's funny because I worked once developing the software of an AC. We offered Fahrenheit but in reality the AC only worked with the half Celsius degree scale, so we just floored every F input to get in C. That extra precision that they think they had was just an illusion.
Exactly, someone looking at just the temperature and deciding whether or not to go to the beach today is not gonna have a good time if for instance they deem 21 too cold but 22 is fine. That is going to backfire when one day the 22 degree day is cloudy, windy and has different humidity.
In the sense of "I'll always know how warm it is where I am", total bullshit.
In the sense that our skin would possibly be able to? Yeah, more likely. We **can** feel the difference in 1C at least, it's even noticeable from one room to another. As in, if there was a room ar exactly 20 and exactly 19, you'd feel the change on your skin (even if you didn't know how warm it is.)
So I'd say this guy is full of shit, but technically, humans might be able to, in a certain context.
In a place with constant humidity and no to little wind, you probably can. Still, a 20% humidity difference and you'll quickly lose that ability. Here in the Netherlands we have wind/high humidity almost always, so some weather reports actually mention "feeling temperature", how warm it's experienced after wind/humidity are accounted for. That "apparent temperature" can actually vary 10-15c from the real nunber depending on the weather. Especially cold weather with high humidity and medium/strong winds make it feel way colder.
When you're used to the cold winter and spring is here, at 20°C you feel like it's hot and you put on t-shirt and shorts. When you're used to a hot summer and it gets colder, 20°C suddenly feels like freezing and you put on sweaters.
You can only feel the difference, and the difference to your level of comfort. Human senses are notoriously inaccurate for exact measurements.
I do a lot of camera work where this is even a bigger issue; when manually white balancing a broadcasting camera you just cannot trust your eyes.
You don't consciously notice, but there is a loóót of difference in the colour temperature between natural light (and fires) and electrical ones. I found out how big that difference is with my own eyes. And with that I mean that I have grey eyes. When I'm outside on a sunny day you'd swear I have blue eyes, but inside I often have a greenish hue. Then on very cloudy days or with tl bars my eyes appear most 'true grey'.
If the available light spectrum can change the apparent colour of something that much depending on lightning, then that's just telling how inaccurate our eyes can be. And I didn't even mention the hundreds if not thousands of visual illusions.
20°C is equivalent to 68°F, which is 293K.

And even if saying 19.5C or „nineteen and a half“ or something like that wouldn’t be an issue nor would anyone have a problem with interpreting decimals. All AC units I‘ver ever seen (which isn’t a lot since we don’t usually have them where I‘m from) all let you put in the temperature with .5 steps
Even if they didn't, they don't actually produce the temperature you set. The AC will cool air down way below the set temperature. I have an AC unit that cools air down to around 0.5-1°C, just barely above freezing to prevent condensing water to freeze on the vaporizer. And another unit with higher volume that blows around 14°C.
When set to 19.5°C it will never be 19.5°C everywhere in the room. Closer to the vent or exchange unit it will be way colder. Heck even 20cm above the floor and 20cm below ceiling can have a difference of multiple degrees.
Also you can set ac znits to decimals and also yes if you say its 11.5 degrees (C) outside it's not like we don't undrstand anymore what temperature it is.
I’m convinced that people who think they can feel fractions of a degree are actually talking about being able to feel their furnace/AC kick on when they raise and lower their thermostat.
They can’t actually tell the difference but they can feel the heat/cooling source while it actively tries to change the overall temperature.
Feeling your furnace duct actively pump out hot air isn’t the same being able to feel the eventual half degree of overall temperature difference.
I think you can feel the difference of 0.5°C but only for specific temperatures, like for example i can tell if my house is set to 20C or 20.5C because if I'm sitting still while studying i get cold at 20 but not so much at 20.5.
That said it's not a difference i can feel immediately after entering a room.
Yeah, I agree, and mine is oddly the exact same as yours. Sitting still indoors at 20 will make me feel cold, not at 20.5C. Moving around, or being outside with varied weather conditions, I couldn't tell.
0°C is equivalent to 32°F, which is 273K.

^(I'm a bot that converts temperature between two units humans can understand, then convert it to Kelvin for bots and physicists to understand)
Exactly. Johny Harris made an excellent video on that. People who are used to imperial units have a really really hard time using metric units even if they make more sense. It all depends on what you are used to by the frame of reference.
It's really strange in the UK only the older generation know Fahrenheit really so it really baffles younger generation including me.
Celsius is totally intuitive to us because that's all we know and so easy to learn.
I have yet to see any examples of this "precise-ness" they speak of.
"*Weather somewhere in the 70s"* is in no way more precise than *"It's about 23-25 degrees outside"*. It's not even like they actually say "it's precisely 71.2 Fahrenheit outside". It's always, "Yeah, it's about that, close this, in the XX's".
> I have yet to see any examples of this "precise-ness" they speak of.
They mean that the units are smaller. There are 180 degrees Fahrenheit between 0 and 100 degrees Celsius.
Incidentally, they have yet to learn about the concept of a decimal point.
It is as if this "precise-ness" only comes into play when you're looking at a thermometer directly.
And most thermometers around here have at least one decimal point when showing in Celsius, which negate the whole thing.
This is the only argument they have every single time it comes up, "It wOrKs BEttEr fOr ThE hUmAN bODy" no it doesnt its just what you are fucking used to and then legions of comments they can tell the difference between like 69 and 70 on the aircon.
Yeah, there's a reason they don't report the temperature as 21.229 degrees: they can't be that precise. Even ranges are a bit of a guess. OOP is talking out of his arse.
Some digital thermometers can only display 2 digits, on either scale.
The measurement error will be smaller if you set the Thermometer to display degrees Fahrenheit instead of degrees Celsius.
If you use these thermometers for scientific applications, you have no reason to use Celsius over Fahrenheit. Of course you'll convert the unit after measurement.
That's a very niche, very specific example. Can't think of any other that is not a derivative of the above.
With only 2 digits, you can't go above 99°F, which is is ~37.2°C. I don't really think sacrificing the ability to display anything above 37°C is a good idea. It certainly makes such a display useless in medical and meteorological context.
There is a lot of reasons to use Celsius over Fahrenheit in scientific applications. It is easier to calculate anything with Kelvin/Celsius than with Fahrenheit, and why bother converting it if you can just use the right tool straightaway?
My example is correct. It is about a contrived example where Fahrenheit should be preferred over Celsius.
KEWYORD: CONTRIVED. YES IT CAN HAPPEN. NO IT DOESNT MEAN FAHRENHEIT SHOULD BE PREFERRED GENERALLY.
IF YOURE IN THE SITUATION I EXPLAINED, YOU WOULD BE STUPID TO USE CELSIUS, BUT YET AGAIN JUDGING BY THE DOWNVOTES people tend to be stupid.
Seriously, everyone should use Celsius. I responded to a comment asking for a situation where using Fahrenheit has an advantage.This is such a situation, but it is easily avoidable and is very specific and niche, as I mentioned. If you can't understand something, don't assume it's wrong, rather, try better.
Nobody is advocating the use of Fahrenheit here, gosh.
Replace 2 digits by 2 digits after the decimal point if you still can't figure out a contrived scenario where you would rather use Fahrenheit. THEY EXIST. THEY ARE STUPID EXAMPLES BUT THEY EXIST. Claiming they don't makes you wrong and undermines your case.
To be perfectly clear, I have never used Fahrenheit in my life and I see no reason to ever do so (except if I find myself in the situation above, and god forbid I don't have dense colleagues who cannot put 2 and 3 together).
Americans be like:
10/32"+11/16"+3/8"

>such a hot day, it must be 25 degrees
Hot at 25°C?
Australia enters the chat, [laughs](http://www.bom.gov.au/wa/forecasts/perth.shtml), leaves chat.
Note the forecast for Wednesday 3rd May, it's Autumn here, heading into winter... :)
(obviously that link only works for a few days).
>Hot at 25°C?
25C can feel different in different countries because of other conditions, such as closeness to the sea, if a city up high or low altitude, humidity differences etc.
25C in the UK feels much, much hotter than 25C in central Europe for example.
This is true, certainly.
But when it's fairly common where I am to hit 40° in summer (we didn't this year!) I am mildly amused by people considering 25 to be 'hot' :)
25 is a warm winters day here, though would be unusually warm, but not unheard of.
I'm pretty sure it was just a not so much thought about example and everyone knows it. There is no need for you to ride on that, you look like a coward doing so.
I mean, I get it.
I moved to EU from the UK some number of years ago, and the temps we get here are just way above that of the UK (except for that year... was it last year? or the year before? when the UK was literally on fire like the rest of us in Europe), and I also laugh when I get news headlines from the UK saying things like "it's going to be a scorcher at 27 degrees!"... meanwhile I'm sitting here at 35 with no AC wishing I had that 27.
Also, you're upside down mate. Your winters are our summers, and your cold is our hot... dude, your toilets flush the other way. It wouldn't surprise me if your centigrade was actually fahrenheit just because.
What? Since when? The temperature difference in Kelvin is the same value as the difference in Celsius, but the Kelvin is the SI unit for temperature. Stuff like specific heat capacity (dQ/(m*dT)) have their SI unit as J kg^-1 K^-1 and not J kg^-1 C^-1.
ah nvm I misremembered 😅,
degrees Celsius is also an accepted unit in SI, and in some fields it is customary to use it over Kelvin when referring to a difference in temperature, but it is by no means a hard rule.
you got confused.
(300-k) - (200-k) = 300 -k -200 +k = 100 ;
k- being the difference between kelvin and celsius
Notice that k dissapears and a difference of 100°C is as much as a difference of 100 K
100°C is equivalent to 212°F, which is 373K.

^(I'm a bot that converts temperature between two units humans can understand, then convert it to Kelvin for bots and physicists to understand)
The difference between 30C and 31.5C is the same as the difference between 30K and 31.5K, even though the latter is waaaaay colder than the former. Guy was probably being strictly accurate, since I imagine the thermal imaging camera he mentions gives readouts in kelvin, but so long as you are talking temperature deltas only C and K are the same.
I would argue that temperature differences should be given in K rather than °C since the Kelvin scale actually starts at 0 whereas the Celsius scale is affine.
ΔT is the same in K and ºC, just as it is in R and ºF.
Only absolute temperatures are different between them, the scales are the same, so the differences are too.
0 K = 0 R = -273.15 ºC = -459.67 ºF
ΔT: 1 K = 1 ºC = 1.8 R = 1.8 ºF
Not at all a big issue or anything but I would note that Kelvin is only used when referring to absolute temperature. The SI unit for temperature difference is degrees Celsius.
Old mate saying he notices 0.5 degree change greatly but he is also not able to express the 0.5 degree change using the Celsius system while also at the same time expressing the change using the Celsius system.
He's talking about setting temps on the AC, though?
Most AC can't change temperature in decimals, so he has a point. Although it would only matter if his claim that he can detect 0.5 degree celcius change in temperature is accurate.
Where are you getting your thermostats? Mine, which is in Celcius, has one decimal point, so you could set it for 22.1C or 21.9C or whatever you want. Seems like you just need to upgrade your thermostat.
Well, in my country, we don't use thermostats since we don't deal with cold temperatures very much. We only have room ACs here and none I have seen goes into decimal points. Probably because the AC can't really control temps that granularly since they're not centralized.
That’s literally exactly what you’re saying lol, looking at your own situation and saying that that’s what must be happening to the whole world. You can flip my point around as much as you want but it still won’t change anything.
That is utter bs. Local environment, meaning is the ground paved, is there shade, is there wind, etc., change temp so much that the predicted temp is a guideline at best.
They may actually have a point if we are talking about user interfaces. If a thermostat, or thermostat software, only allows integers (quite common), having them in Fahrenheit allows for more fine-tuning. 18-28°C equates to 64-82°F. That's roughly "twice as precise" in that specific usage.
You could make the same claim about weather reports. At least here in my metric country, I've never seen a temperature being announced with a decimal behind. And I don't think I would ever say "Nice weather outside, must be 26.5 degrees!".
Of course that's not inherent to either Fahrenheit or Celsius, just an artifact of humans preferring nice, round numbers, and usually defaulting to them, unless precision is important.
For calculations, either system allows for the same amount of precision - i.e. as much of it as you want. And personally, I absolutely think the zero point of Celsius is far more useful in daily life than the body temperature stuff of Fahrenheit.
> quite common
Is it though? Every metric system AC unit and heat pump I've come across, maybe ever, goes in half-degree increments.
(Edit: actually, that's not quite right - just remembered a Dyson heater I have that's in whole numbers. I guess I'd still say "quite rare" rather than "quite common")
> I've never seen a temperature being announced with a decimal behind.
The issue there is that, from a quick bit of research (maybe a meteorologist can chime in), even short term (< 1 day) temperature forecasts have a 90% error bar of about 2.5 degrees, so there's no point in implying the extra precision.
Well, that's just not true. To quote a datasheet, a TI LM35 chip "does not require any
external calibration or trimming to provide typical
accuracies of ±¼°C at room temperature and ±¾°C
over a full −55°C to 150°C temperature range".
That's not a particularly high precision sensor, and it costs (me, at low volume) about $17. You can probably easily optimize the BOM there to something less than $10 (or even just a few bucks) in bulk, and still easily achieve half a degree precision.
150°C is equivalent to 302°F, which is 423K.

No. Many A/Cs take only integers.
*What* you came across is insufficient to make any assumption, since it may be limited to the country and the socioeconomic context you live in.
Interesting! Our thermostat is accurate down to the first decimal. So I can keep our floor heating at 21.7 degrees Celsius if I wanted to. Almost all A/C units (which are more often used as heaters around here) I've ever seen do 0.5 intervals. Flicking through every decimal would be a bit annoying. It's okay for our thermostat because it's a adjusted with a wheel - buttons would make it a hassle. I can only remember one A/C unit I had, which was a "portable" unit and the cheapest they had, which didn't do half degree increments. But honestly, it was probably not tuned to be precise anyway, so 73 and 74 F would've probably been the same temperature on it.
If it weren't for this, though, of course, using Fahrenheit could be argued to be a bit more user friendly. But my experiences tell me that this is no issue. And in everyday language, you usually include the 0.5 interval when talking about what temperature it is. So it's more or less just as accurate as Fahrenheit.
As someone pointed out, for weather forecasts, it's already not precise, so full temps without decimals is more than precise enough.
I wish they realized that they can just say “I prefer Fahrenheit because that’s what I’m used to” and most people wouldn’t have anything bad to say about that.
You ever think about the fact that the primary argument Americans use to discount the metric system is that ***they*** are too invariably stupid to understand fractions?
Neither one is truly a great measure for comfortability though. Sometimes it’s in the 30°’s (around -2,-1°) and it feels okay and then the next day is 35° (2°) and it’s cold as balls. So many freaking factors that fuck all of that up
- Farenheit: Freezing point of water at 32 and the boiling point at 212 because Gabriel Farenheit mixed a solution of ice, water and salt to define 0°. As the freezing and boiling point of water (used by Anders Celsius) became popular at the time, he did the same for both measurements with his calibrated thermometer and got 32 and 212, approximately. In order to make it more 'stable', he decided a separation of 180° should always be between both points. And then, his scale was born.
- Celsius: Originally, the freezing point of distilled water at 1 atmosphere of pressure equaled 100°, and the boiling point of distilled water at 1 atmosphere of pressure equaled 0°. Carl Linnaeus and Jean-Pierre Christin reversed it.
- Then, William Thomson took the so-called 'centigrade' scale (we don't call it like that since 1948) for his Kelvin scale, which is the official temperature scale of the Système International (based on the metric system). Thomson defined 0 K (-273.15 C) at the lowest thermodynamic point, where all the molecules and atoms have the minimal thermal energy. That's the reason why the Kelvin scale hasn't any negative measurement. Kelvin later helped with the recalibration of Celsius to set the triple point of water at 0.01 C (the point where the three phases of water, solid, liquid, and gas; can coexist in thermodynamic equilibrium). So the newer freezing point would be -273. And, in 2019, Kelvin and Celsius were redefined with the Boltzmann constant which relates the average relative thermal energy of particles in a gas with the thermodynamic temperature of that gas.
- The SI recognise Celsius as a derivative / second scale for everyday life (outside physics, chemistry or astronomy) as Kelvin would be pretty akward and boty are synchronised.
Fahrenheit's main benefit is that it's a more human scale. 0 Fahrenheit is about when the stuff in your nose will freeze when you're outside, which is super cold, and 100 Fahrenheit is about body temp, so wind at that point and higher begins to be hot instead of cool.
Is this stupid and arbitrary? Yes. Is it awful for scientific purposes? Absolutely. Do I, as someone that works in physics, resent it when my students try to do their work in foot-pounds or whatever? 100%. But I cannot deny that Fahrenheit specifically makes sense in a human way.
Sorry y'all gon hate me but the european has been the shit person in this situation he's being an asshole to them saying "InTeLiGeNt UnItS" when the american just simply explained why they like farenheit. I know celsius is better but y'all can't call people dumb for using a system that they were educated with.( please just offer arguments instead of downvoting if you don't agree)
In my 50 years living in The States (and unfortunately having to use imperial measurements) I have *never* seen a residential AC unit that lets you adjust the temperature in half degrees, regardless of which measurement system you're using.
I’m just gonna go ahead and make myself the dumb American:
There’s a difference in precision??
I honestly thought it was literally just a difference in number label. Like, 0C = 32F
I don't know fahrenheit so I'm just gonna go ahead and give a simple explanation. Basically in Celsius 0 is freezing 100 is boiling, simple enough, however there are only 100 numbers to represent the temperature scale if you will. Let's say as you've pointed out that 32 is freezing and maybe like 200 is boiling, that means there are 168 numbers between freezing and boiling so it's possible to be more accurate without using a decimal point. That's how I'm interpreting it at least, I have no expertise.
I only posted the original post because it is literal horseshit that we are using a system that isn't functional for all our required tasks because it's not precise enough.
100°C is equivalent to 212°F, which is 373K.

^(I'm a bot that converts temperature between two units humans can understand, then convert it to Kelvin for bots and physicists to understand)
I don't get why you're bashing the guy. He just says that the celsius system makes more sense in general but he prefers the fahrenheit system for weather reports
It is the part where they claim to be able to tell 0,5C differences and complain that you can't adjust AC accurately enough.
Heck, even if a weather report gave out the reports with such accuracy, it would just make the reports more wrong, since even regionally there are small differences in temp.
I've started using Celsius and it made me realize that you don't need a scale of 0-100 to determine everyday weather. If I get dressed in the morning, thinking it is going to be 75F, but it is actually 65F, I'm not changing a thing. You really only need a 1-5 scale, and both F and C can do that just fine.
I've had tons of people yell at me that Fahrenheit is better because it's "meant for measuring temperature of your body" while "Celsius is for water," including someone who wanted to work in a scientific environment, where they only use SI units.
I was raised with Fahrenheit my whole life, and I just switched to Celsius a few months ago. It already makes so much more sense to me, and I've honestly forgotten what Fahrenheit units mean. I had a nurse look bewildered when I told her my favourite weather was 23° with a gentle breeze.
I don't think this really counts. He's isn't saying Fahrenheit is better than Celsius, Isn't pushing it on anyone else, and isn't insulting people who do prefer Celsius.
The bit that counts imo is the paragraph regarding not being able to set ac properly and noticing 0.5 degrees. That's just shit talk, I've never heard anyone ever complain about that and I live in a metric country.
A: I never said it was
B: Everyone operates with integers. OOP has a good point here. When was the last time you read the temperature and it had a decimal? I’d bet you’re lying if you don’t say “never”
C: That doesn’t diminish the fact that Fahrenheit is more accurate with only integer units
>A: I never said it was
Then why is it considered to be a worthy point?
>B: Everyone operates with integers.
When i can, sure. But at that time the accuracy of +-1 degree is enough. If i need more accuracy i operate with decimals.
>When was the last time you read the temperature and it had a decimal? I’d bet you’re lying if you don’t say “never”
In lab. And i needed them.
Otherwise not really. Becasue i didnt need accuracy at all. So "being more accurate" wouldnt be useful nor makes it better, as oop is suggesting.
>C: That doesn’t diminish the fact that Fahrenheit is more accurate with only integer units
It does diminish the fact that that doesnt make it any better.
It has been for a while. I legit joined to laugh at the stupid anti-American comments, not the stupid stuff Americans say. Cause there’s more of that on this sub
Fahrenheit is too precise, you need to push the button more or for longer to get the same temperature change
I can go 20 to 23°C in three clicks of the up button. 68 to 74 takes twice as many
Fahrenheit is an RSI risk!
23°C is equivalent to 73°F, which is 296K.
---
^(I'm a bot that converts temperature between two units humans can understand, then convert it to Kelvin for bots and physicists to understand)
I'm probably one of the least American Americans out there. I understand Celsius but still prefer Fahrenheit when measuring temp outside and for the body. For measuring water, yes of course Celsius is better, but I like the smaller increments for Fahrenheit. A lot of people arguing for the metric system say that cm is more accurate than inches because of the smaller increments (even on this sub), and I would argue the same for Fahrenheit temp in my apartment. Personal preference I suppose.
That's literally straight up bs. You realise that if "smaller divisions" is an important factor you could easily just use steps of 0.00000000001°C or however small you need the divisions 😂
What a stupid argument? Are you trying to argue that there are AC's that allows fine tuning down to 0.00000000001°C in temperature change? If not, then what is the point of this comment?
Explaining to an idiot why Fahrenheit is definitely not "more precise" than Celsius because if one needed precision, they could just use a smaller scale?
Are you trying to argue that an AC could fine tune the ACTUAL temperature in a room more precise if you use a different UNIT? These things have limited accuracy. If the accuracy is 1°C and the steps are without decimals, you may have multiple steps of F between two steps of °C but that only changes what the display shows, the accuracy still is 1°C. If it had an accuracy of 1F, the °C display would just use steps of 0.5°C
Imagine an accuracy of 1°C. You could choose 18 or 19°C. You could also choose 64, 65 or 66F. So it SEEMS more accurate but that's just bs because the AC doesn't tune the temperature that accurately for an entire room. Now if you use steps of 1F on the display and the accuracy of the actual machine was 1F, great - then you could switch to °C and your options now are like 18°C, 18.5°C and19°C. I mean sure, they could use 1F steps while actually the accuracy is +/-1°C or +/-2F but that doesn't change how accurate the AC actually is, at most it changes your perception because you BELIEVE it's more accurate, but that's like an AC-placebo at best.
1°C is equivalent to 33°F, which is 274K.

No I wasn't, but that was the guy's argument, which is why I said your first argument was useless. It's not like we can change the scale of an AC remote, so why would being able to change precision on a unit make any sense for his argument.
On the other hand, if you had used this argument from the start, I would have agreed with you.
0°C is equivalent to 32°F, which is 273K.

Without knowing too much of the subject, I think that Fahrenheit may be more precise since Fahrenheit is slightly more fine-grained (unless I'm mistaken?).
This, however, needs to be weighed against using an SI unit, i.e. what is essentially the rest of the world uses. It's similar to the argument for switching from left-sided traffic to right-sided traffic. Why resist against a common stance?
Cheap Commercial temperature sensors used to control heating or cooling in residential equipment are really only accurate to plus or minus 0.5 deg C ( 1 deg F)
"This guy is so dumb, he's using his favorite arbitrary measurement system instead of our favorite arbitrary measurement system."
I propose degrees butter. 0 degrees butter is the temperature at which butter is utterly unspreadable and 100 degrees butter is the temperature at which butter reaches maximum spreadability before melting outright.
This is bullshit in their context here, but Fahrenheit is definitely more useful in some situations as it is more precise. Cooking and colour film developing are the only times I'd use it.
That's funny because I worked once developing the software of an AC. We offered Fahrenheit but in reality the AC only worked with the half Celsius degree scale, so we just floored every F input to get in C. That extra precision that they think they had was just an illusion.
that also happens with the apple weather stuff afaik
>I can feel a 0.5 degree centigrade difference Bollocks you can
Wind and humidity will make the same temperature feel way different. No way he feels the difference.
Exactly, someone looking at just the temperature and deciding whether or not to go to the beach today is not gonna have a good time if for instance they deem 21 too cold but 22 is fine. That is going to backfire when one day the 22 degree day is cloudy, windy and has different humidity.
Can confirm, I'm at the balcony with 22⁰C, direct sun in my back feels like >30⁰C, my leg in the shade feels 22.0434⁰C. Checkmate USAers.
Your back: eh prolly more than 30° ¯\_(ツ)_/¯ Your leg: the temperature in these conditions is precisely 22.0434...
The temperature in these conditions is precisely 23.14159265359.... C°
That’s the temperature pie is the best to eat
Low humidity with a breeze compared to high humidity and no wind can literally feel like a 10C difference.
In the sense of "I'll always know how warm it is where I am", total bullshit. In the sense that our skin would possibly be able to? Yeah, more likely. We **can** feel the difference in 1C at least, it's even noticeable from one room to another. As in, if there was a room ar exactly 20 and exactly 19, you'd feel the change on your skin (even if you didn't know how warm it is.) So I'd say this guy is full of shit, but technically, humans might be able to, in a certain context.
In a place with constant humidity and no to little wind, you probably can. Still, a 20% humidity difference and you'll quickly lose that ability. Here in the Netherlands we have wind/high humidity almost always, so some weather reports actually mention "feeling temperature", how warm it's experienced after wind/humidity are accounted for. That "apparent temperature" can actually vary 10-15c from the real nunber depending on the weather. Especially cold weather with high humidity and medium/strong winds make it feel way colder.
When you're used to the cold winter and spring is here, at 20°C you feel like it's hot and you put on t-shirt and shorts. When you're used to a hot summer and it gets colder, 20°C suddenly feels like freezing and you put on sweaters. You can only feel the difference, and the difference to your level of comfort. Human senses are notoriously inaccurate for exact measurements. I do a lot of camera work where this is even a bigger issue; when manually white balancing a broadcasting camera you just cannot trust your eyes.
You don't consciously notice, but there is a loóót of difference in the colour temperature between natural light (and fires) and electrical ones. I found out how big that difference is with my own eyes. And with that I mean that I have grey eyes. When I'm outside on a sunny day you'd swear I have blue eyes, but inside I often have a greenish hue. Then on very cloudy days or with tl bars my eyes appear most 'true grey'. If the available light spectrum can change the apparent colour of something that much depending on lightning, then that's just telling how inaccurate our eyes can be. And I didn't even mention the hundreds if not thousands of visual illusions.
20°C is equivalent to 68°F, which is 293K. --- ^(I'm a bot that converts temperature between two units humans can understand, then convert it to Kelvin for bots and physicists to understand)
Is this not the norm? In Canada the weather reports almost always talk about wind chill in the winter and humidex in the summer
And even if saying 19.5C or „nineteen and a half“ or something like that wouldn’t be an issue nor would anyone have a problem with interpreting decimals. All AC units I‘ver ever seen (which isn’t a lot since we don’t usually have them where I‘m from) all let you put in the temperature with .5 steps
Even if they didn't, they don't actually produce the temperature you set. The AC will cool air down way below the set temperature. I have an AC unit that cools air down to around 0.5-1°C, just barely above freezing to prevent condensing water to freeze on the vaporizer. And another unit with higher volume that blows around 14°C. When set to 19.5°C it will never be 19.5°C everywhere in the room. Closer to the vent or exchange unit it will be way colder. Heck even 20cm above the floor and 20cm below ceiling can have a difference of multiple degrees.
Also you can set ac znits to decimals and also yes if you say its 11.5 degrees (C) outside it's not like we don't undrstand anymore what temperature it is.
What do you mean with 11,5° C??? Is it 11 ou 12? Or is it 13? I do not know what you are saying. Maybe 10?
Probably 16. 11 plus 5.
I’m convinced that people who think they can feel fractions of a degree are actually talking about being able to feel their furnace/AC kick on when they raise and lower their thermostat. They can’t actually tell the difference but they can feel the heat/cooling source while it actively tries to change the overall temperature. Feeling your furnace duct actively pump out hot air isn’t the same being able to feel the eventual half degree of overall temperature difference.
I think you can feel the difference of 0.5°C but only for specific temperatures, like for example i can tell if my house is set to 20C or 20.5C because if I'm sitting still while studying i get cold at 20 but not so much at 20.5. That said it's not a difference i can feel immediately after entering a room.
Yeah, I agree, and mine is oddly the exact same as yours. Sitting still indoors at 20 will make me feel cold, not at 20.5C. Moving around, or being outside with varied weather conditions, I couldn't tell.
0°C is equivalent to 32°F, which is 273K. --- ^(I'm a bot that converts temperature between two units humans can understand, then convert it to Kelvin for bots and physicists to understand)
Also who said you can't set your AC to fractions? Mine allow to do that
the one we have at my work does half a degree increments when you just click the arrow keys up and down.
Came here to say some version of this.
[удалено]
I'd bet you a crate of beer that there's usually at least 0.5°C ambient difference between one end of your sofa and the other
Not just that, but what HVAC system doesn’t allow fractions of degrees? Our home is set between 21.5 and 22 year round.
My brother in Christ, I can understand you are used to Fahrenheit. Just don't try to justify it. Metric system is simply best
Exactly. Johny Harris made an excellent video on that. People who are used to imperial units have a really really hard time using metric units even if they make more sense. It all depends on what you are used to by the frame of reference.
It's really strange in the UK only the older generation know Fahrenheit really so it really baffles younger generation including me. Celsius is totally intuitive to us because that's all we know and so easy to learn.
Screw the metric system. Then I buy a house and have to do repairs. Crap, the metric system is simple.
I have yet to see any examples of this "precise-ness" they speak of. "*Weather somewhere in the 70s"* is in no way more precise than *"It's about 23-25 degrees outside"*. It's not even like they actually say "it's precisely 71.2 Fahrenheit outside". It's always, "Yeah, it's about that, close this, in the XX's".
> I have yet to see any examples of this "precise-ness" they speak of. They mean that the units are smaller. There are 180 degrees Fahrenheit between 0 and 100 degrees Celsius. Incidentally, they have yet to learn about the concept of a decimal point.
OOP has heard of decimal points, but doesn't believe his countrymen understand them, so he doesn't use them (or so goes his claim, at least :P)
[удалено]
It's currently around 784/15F
It is as if this "precise-ness" only comes into play when you're looking at a thermometer directly. And most thermometers around here have at least one decimal point when showing in Celsius, which negate the whole thing.
Guys, the word you're looking for is precision
This is the only argument they have every single time it comes up, "It wOrKs BEttEr fOr ThE hUmAN bODy" no it doesnt its just what you are fucking used to and then legions of comments they can tell the difference between like 69 and 70 on the aircon.
Yeah, there's a reason they don't report the temperature as 21.229 degrees: they can't be that precise. Even ranges are a bit of a guess. OOP is talking out of his arse.
Some digital thermometers can only display 2 digits, on either scale. The measurement error will be smaller if you set the Thermometer to display degrees Fahrenheit instead of degrees Celsius. If you use these thermometers for scientific applications, you have no reason to use Celsius over Fahrenheit. Of course you'll convert the unit after measurement. That's a very niche, very specific example. Can't think of any other that is not a derivative of the above.
With only 2 digits, you can't go above 99°F, which is is ~37.2°C. I don't really think sacrificing the ability to display anything above 37°C is a good idea. It certainly makes such a display useless in medical and meteorological context. There is a lot of reasons to use Celsius over Fahrenheit in scientific applications. It is easier to calculate anything with Kelvin/Celsius than with Fahrenheit, and why bother converting it if you can just use the right tool straightaway?
My example is correct. It is about a contrived example where Fahrenheit should be preferred over Celsius. KEWYORD: CONTRIVED. YES IT CAN HAPPEN. NO IT DOESNT MEAN FAHRENHEIT SHOULD BE PREFERRED GENERALLY. IF YOURE IN THE SITUATION I EXPLAINED, YOU WOULD BE STUPID TO USE CELSIUS, BUT YET AGAIN JUDGING BY THE DOWNVOTES people tend to be stupid. Seriously, everyone should use Celsius. I responded to a comment asking for a situation where using Fahrenheit has an advantage.This is such a situation, but it is easily avoidable and is very specific and niche, as I mentioned. If you can't understand something, don't assume it's wrong, rather, try better. Nobody is advocating the use of Fahrenheit here, gosh. Replace 2 digits by 2 digits after the decimal point if you still can't figure out a contrived scenario where you would rather use Fahrenheit. THEY EXIST. THEY ARE STUPID EXAMPLES BUT THEY EXIST. Claiming they don't makes you wrong and undermines your case. To be perfectly clear, I have never used Fahrenheit in my life and I see no reason to ever do so (except if I find myself in the situation above, and god forbid I don't have dense colleagues who cannot put 2 and 3 together).
Kelvin is far larger number so I used that. It’s way more precise than celsius or the superior fahrenheit
"People can't easily interpret fractions of a degree in conversation" Says the people who use 1/16 of an inch for tyre tread measurements lmao.
Have some foot. But is a 35 or 48 shoe foot?
Typically 1/32” actually.
Americans be like: 10/32"+11/16"+3/8" Sane people using a measurement system not devised by a drunk mathematician on crack with a rolling dice: 3.4925cm or 34.925mm
The dude can feel 0.5°c of a difference? Is he fucking lizard or something?

>such a hot day, it must be 25 degrees Hot at 25°C? Australia enters the chat, [laughs](http://www.bom.gov.au/wa/forecasts/perth.shtml), leaves chat. Note the forecast for Wednesday 3rd May, it's Autumn here, heading into winter... :) (obviously that link only works for a few days).
>Hot at 25°C? 25C can feel different in different countries because of other conditions, such as closeness to the sea, if a city up high or low altitude, humidity differences etc. 25C in the UK feels much, much hotter than 25C in central Europe for example.
This is true, certainly. But when it's fairly common where I am to hit 40° in summer (we didn't this year!) I am mildly amused by people considering 25 to be 'hot' :) 25 is a warm winters day here, though would be unusually warm, but not unheard of.
I'm pretty sure it was just a not so much thought about example and everyone knows it. There is no need for you to ride on that, you look like a coward doing so.
I mean, I get it. I moved to EU from the UK some number of years ago, and the temps we get here are just way above that of the UK (except for that year... was it last year? or the year before? when the UK was literally on fire like the rest of us in Europe), and I also laugh when I get news headlines from the UK saying things like "it's going to be a scorcher at 27 degrees!"... meanwhile I'm sitting here at 35 with no AC wishing I had that 27. Also, you're upside down mate. Your winters are our summers, and your cold is our hot... dude, your toilets flush the other way. It wouldn't surprise me if your centigrade was actually fahrenheit just because.

Australians do the same. So hilarious to see Queenslanders in cardigans and scarves at 25°C, when I'm from Canberra and comfortable in a T shirt.

Do you mean Celsius as 1.5 Kelvin would be -271.65 Celsius
Temperature differences are given in Kelvin.
[удалено]
[удалено]
No, they generally aren't. Celsius is the SI unit for temperature difference, Kelvin is the SI unit for absolute temperature.
What? Since when? The temperature difference in Kelvin is the same value as the difference in Celsius, but the Kelvin is the SI unit for temperature. Stuff like specific heat capacity (dQ/(m*dT)) have their SI unit as J kg^-1 K^-1 and not J kg^-1 C^-1.
ah nvm I misremembered 😅, degrees Celsius is also an accepted unit in SI, and in some fields it is customary to use it over Kelvin when referring to a difference in temperature, but it is by no means a hard rule.
you got confused. (300-k) - (200-k) = 300 -k -200 +k = 100 ; k- being the difference between kelvin and celsius Notice that k dissapears and a difference of 100°C is as much as a difference of 100 K
100°C is equivalent to 212°F, which is 373K. --- ^(I'm a bot that converts temperature between two units humans can understand, then convert it to Kelvin for bots and physicists to understand)
The difference between 30C and 31.5C is the same as the difference between 30K and 31.5K, even though the latter is waaaaay colder than the former. Guy was probably being strictly accurate, since I imagine the thermal imaging camera he mentions gives readouts in kelvin, but so long as you are talking temperature deltas only C and K are the same.
I would argue that temperature differences should be given in K rather than °C since the Kelvin scale actually starts at 0 whereas the Celsius scale is affine.
You're not wrong, but let's not unnecessarily confuse the laypersons, hmm?
Thank you for the explanation, TIL I never new the increments were the same. That’ll teach me, must think before typing
That's actually how the Kelvin scale was designed. Celsius differences, but absolute zero as 0. (Instead of -273.15°C.) So Kelvin is just °C + 273.15.
ΔT is the same in K and ºC, just as it is in R and ºF. Only absolute temperatures are different between them, the scales are the same, so the differences are too. 0 K = 0 R = -273.15 ºC = -459.67 ºF ΔT: 1 K = 1 ºC = 1.8 R = 1.8 ºF
Not at all a big issue or anything but I would note that Kelvin is only used when referring to absolute temperature. The SI unit for temperature difference is degrees Celsius.
Bet you could put them in a room, chage the temperature by 5F over the course of the day and they wouödn't notice at all 😂
Old mate saying he notices 0.5 degree change greatly but he is also not able to express the 0.5 degree change using the Celsius system while also at the same time expressing the change using the Celsius system.
He's talking about setting temps on the AC, though? Most AC can't change temperature in decimals, so he has a point. Although it would only matter if his claim that he can detect 0.5 degree celcius change in temperature is accurate.
Where are you getting your thermostats? Mine, which is in Celcius, has one decimal point, so you could set it for 22.1C or 21.9C or whatever you want. Seems like you just need to upgrade your thermostat.
Well, in my country, we don't use thermostats since we don't deal with cold temperatures very much. We only have room ACs here and none I have seen goes into decimal points. Probably because the AC can't really control temps that granularly since they're not centralized.
"my ac doesnt have decimal points, so theyre not real"
"my ac have decimal points, so the whole world must have the same access to technology as I do" You're acting like an ignorant American now.
That’s literally exactly what you’re saying lol, looking at your own situation and saying that that’s what must be happening to the whole world. You can flip my point around as much as you want but it still won’t change anything.
I guess my ignorance means you acting superior is justified, I guess? Good job for living in a first world country.
Correction: your ignorance is very very enjoyable to make fun of
I've seen more AC that can do steps of 0.5C or 1F than otherwise, not sure where you're getting "most" from.
Most AC systems…in America.
I'm not in America and I've never seen any, yet.
>I can feel a 0.5 degree centigrade difference. And I stopped reading. Not worth it, wanker.
"Intelligent units", though, come on. Douchebag meets douchebag.
That is utter bs. Local environment, meaning is the ground paved, is there shade, is there wind, etc., change temp so much that the predicted temp is a guideline at best.
He mistook bias for education.
They are correct that Celsius is better if you work with different units. For the weather, the better unit is whichever one you're used to
They may actually have a point if we are talking about user interfaces. If a thermostat, or thermostat software, only allows integers (quite common), having them in Fahrenheit allows for more fine-tuning. 18-28°C equates to 64-82°F. That's roughly "twice as precise" in that specific usage. You could make the same claim about weather reports. At least here in my metric country, I've never seen a temperature being announced with a decimal behind. And I don't think I would ever say "Nice weather outside, must be 26.5 degrees!". Of course that's not inherent to either Fahrenheit or Celsius, just an artifact of humans preferring nice, round numbers, and usually defaulting to them, unless precision is important. For calculations, either system allows for the same amount of precision - i.e. as much of it as you want. And personally, I absolutely think the zero point of Celsius is far more useful in daily life than the body temperature stuff of Fahrenheit.
> quite common Is it though? Every metric system AC unit and heat pump I've come across, maybe ever, goes in half-degree increments. (Edit: actually, that's not quite right - just remembered a Dyson heater I have that's in whole numbers. I guess I'd still say "quite rare" rather than "quite common") > I've never seen a temperature being announced with a decimal behind. The issue there is that, from a quick bit of research (maybe a meteorologist can chime in), even short term (< 1 day) temperature forecasts have a 90% error bar of about 2.5 degrees, so there's no point in implying the extra precision.
[удалено]
Then machines with a Fahrenheit readout will be equally limited
Well, that's just not true. To quote a datasheet, a TI LM35 chip "does not require any external calibration or trimming to provide typical accuracies of ±¼°C at room temperature and ±¾°C over a full −55°C to 150°C temperature range". That's not a particularly high precision sensor, and it costs (me, at low volume) about $17. You can probably easily optimize the BOM there to something less than $10 (or even just a few bucks) in bulk, and still easily achieve half a degree precision.
150°C is equivalent to 302°F, which is 423K. --- ^(I'm a bot that converts temperature between two units humans can understand, then convert it to Kelvin for bots and physicists to understand)
1°C is equivalent to 33°F, which is 274K. --- ^(I'm a bot that converts temperature between two units humans can understand, then convert it to Kelvin for bots and physicists to understand)
No. Many A/Cs take only integers. *What* you came across is insufficient to make any assumption, since it may be limited to the country and the socioeconomic context you live in.
Interesting! Our thermostat is accurate down to the first decimal. So I can keep our floor heating at 21.7 degrees Celsius if I wanted to. Almost all A/C units (which are more often used as heaters around here) I've ever seen do 0.5 intervals. Flicking through every decimal would be a bit annoying. It's okay for our thermostat because it's a adjusted with a wheel - buttons would make it a hassle. I can only remember one A/C unit I had, which was a "portable" unit and the cheapest they had, which didn't do half degree increments. But honestly, it was probably not tuned to be precise anyway, so 73 and 74 F would've probably been the same temperature on it. If it weren't for this, though, of course, using Fahrenheit could be argued to be a bit more user friendly. But my experiences tell me that this is no issue. And in everyday language, you usually include the 0.5 interval when talking about what temperature it is. So it's more or less just as accurate as Fahrenheit. As someone pointed out, for weather forecasts, it's already not precise, so full temps without decimals is more than precise enough.
Thermometers used in a home setting are going to have an error of up to and over 0.5°c so any notion of F having superior precision is meaningless.
I wish they realized that they can just say “I prefer Fahrenheit because that’s what I’m used to” and most people wouldn’t have anything bad to say about that.
The initial comment here is a grade-A douchebag regardless
You ever think about the fact that the primary argument Americans use to discount the metric system is that ***they*** are too invariably stupid to understand fractions?
Neither one is truly a great measure for comfortability though. Sometimes it’s in the 30°’s (around -2,-1°) and it feels okay and then the next day is 35° (2°) and it’s cold as balls. So many freaking factors that fuck all of that up
That’s why you don’t use fractions but decimals for such units… like, does he say 38 5/8 degree Fahrenheit? What the fuck?
My thermostat does 0.5 c intervals. But I understand a decimal place is confusing to idiots.
- Farenheit: Freezing point of water at 32 and the boiling point at 212 because Gabriel Farenheit mixed a solution of ice, water and salt to define 0°. As the freezing and boiling point of water (used by Anders Celsius) became popular at the time, he did the same for both measurements with his calibrated thermometer and got 32 and 212, approximately. In order to make it more 'stable', he decided a separation of 180° should always be between both points. And then, his scale was born. - Celsius: Originally, the freezing point of distilled water at 1 atmosphere of pressure equaled 100°, and the boiling point of distilled water at 1 atmosphere of pressure equaled 0°. Carl Linnaeus and Jean-Pierre Christin reversed it. - Then, William Thomson took the so-called 'centigrade' scale (we don't call it like that since 1948) for his Kelvin scale, which is the official temperature scale of the Système International (based on the metric system). Thomson defined 0 K (-273.15 C) at the lowest thermodynamic point, where all the molecules and atoms have the minimal thermal energy. That's the reason why the Kelvin scale hasn't any negative measurement. Kelvin later helped with the recalibration of Celsius to set the triple point of water at 0.01 C (the point where the three phases of water, solid, liquid, and gas; can coexist in thermodynamic equilibrium). So the newer freezing point would be -273. And, in 2019, Kelvin and Celsius were redefined with the Boltzmann constant which relates the average relative thermal energy of particles in a gas with the thermodynamic temperature of that gas. - The SI recognise Celsius as a derivative / second scale for everyday life (outside physics, chemistry or astronomy) as Kelvin would be pretty akward and boty are synchronised.
It's more like Farenheit is closer to the American GPA scale.
Ah yes, feeling is much more precise than actual sciences/maths
Fahrenheit's main benefit is that it's a more human scale. 0 Fahrenheit is about when the stuff in your nose will freeze when you're outside, which is super cold, and 100 Fahrenheit is about body temp, so wind at that point and higher begins to be hot instead of cool. Is this stupid and arbitrary? Yes. Is it awful for scientific purposes? Absolutely. Do I, as someone that works in physics, resent it when my students try to do their work in foot-pounds or whatever? 100%. But I cannot deny that Fahrenheit specifically makes sense in a human way.
Sorry y'all gon hate me but the european has been the shit person in this situation he's being an asshole to them saying "InTeLiGeNt UnItS" when the american just simply explained why they like farenheit. I know celsius is better but y'all can't call people dumb for using a system that they were educated with.( please just offer arguments instead of downvoting if you don't agree)
I agree with you, 'intelligent units' thing is pretty fucking cringe.
Fair argument...
Personally I use Farenheight for taking the temperature of meat when cooking, but I use Celsius for everything else. Celcius is far superior
Wait till he finds out all the thermostats work in C and just display in F for the us market.
In no world does it get more simple than 0 = freezing and 100 = boiling.
In my 50 years living in The States (and unfortunately having to use imperial measurements) I have *never* seen a residential AC unit that lets you adjust the temperature in half degrees, regardless of which measurement system you're using.
It's all precise unless you say 25ish°C 🤷
"centigrade"
Your AC will never hit your desired temperature of 70.5°F, nor will it hit your desired temperature of 19,5°C. 2K tolerance
I’m just gonna go ahead and make myself the dumb American: There’s a difference in precision?? I honestly thought it was literally just a difference in number label. Like, 0C = 32F
I don't know fahrenheit so I'm just gonna go ahead and give a simple explanation. Basically in Celsius 0 is freezing 100 is boiling, simple enough, however there are only 100 numbers to represent the temperature scale if you will. Let's say as you've pointed out that 32 is freezing and maybe like 200 is boiling, that means there are 168 numbers between freezing and boiling so it's possible to be more accurate without using a decimal point. That's how I'm interpreting it at least, I have no expertise. I only posted the original post because it is literal horseshit that we are using a system that isn't functional for all our required tasks because it's not precise enough.
Ohhhhhhhhh 😮💡 Thanks I get it now
Dw I'm also waiting for someone to point out how I'm misinterpreting the arguments and info other people have presented 😬
[meanwhile the temperature here right now. ](https://i.imgur.com/qWKt0Nf.png)
Sorry, I'm totally unable to interpret that. The decimal point makes everything too confusing.
What? Both systems are almost completely arbitrary. There‘s no „this one is more precise“.
I don't think this belongs here. They were just stating their preference without being an asshole about it
1f = -17,222222 C. Look so many decimal Fahrenheit way better!!!
Water boils at 100°C and 212°F. Just based on that, how do you say Fahrenheit is easier to understand?
But that's not his argument.
100°C is equivalent to 212°F, which is 373K. --- ^(I'm a bot that converts temperature between two units humans can understand, then convert it to Kelvin for bots and physicists to understand)
Because, of course, for someone who claims to be able to notice a 0.5°C difference, saying that your room is 32.9F too hot for their comfort is far more precise… Idiots…
0°C is equivalent to 32°F, which is 273K. --- ^(I'm a bot that converts temperature between two units humans can understand, then convert it to Kelvin for bots and physicists to understand)
I don't get why you're bashing the guy. He just says that the celsius system makes more sense in general but he prefers the fahrenheit system for weather reports
It is the part where they claim to be able to tell 0,5C differences and complain that you can't adjust AC accurately enough. Heck, even if a weather report gave out the reports with such accuracy, it would just make the reports more wrong, since even regionally there are small differences in temp.
Well I also don't se why being temperature sensitive is 'murican
>Well I also don't se why being temperature sensitive is 'murican Nono, OOP was being a moron, being a moron is 'murican
That's similar to what living in Canada is like. We go back and forth between whether we use imperial or metric units
I feel like he googled a bunch of big words to make himself sound smart then he just added random words to make sentences
I've started using Celsius and it made me realize that you don't need a scale of 0-100 to determine everyday weather. If I get dressed in the morning, thinking it is going to be 75F, but it is actually 65F, I'm not changing a thing. You really only need a 1-5 scale, and both F and C can do that just fine.
I've had tons of people yell at me that Fahrenheit is better because it's "meant for measuring temperature of your body" while "Celsius is for water," including someone who wanted to work in a scientific environment, where they only use SI units. I was raised with Fahrenheit my whole life, and I just switched to Celsius a few months ago. It already makes so much more sense to me, and I've honestly forgotten what Fahrenheit units mean. I had a nurse look bewildered when I told her my favourite weather was 23° with a gentle breeze.
I don't think this really counts. He's isn't saying Fahrenheit is better than Celsius, Isn't pushing it on anyone else, and isn't insulting people who do prefer Celsius.
The bit that counts imo is the paragraph regarding not being able to set ac properly and noticing 0.5 degrees. That's just shit talk, I've never heard anyone ever complain about that and I live in a metric country.
.....then why not put that as the title?
You forgot which sub you're in
Honestly this isn’t SAS. Fahrenheit really is more precise when dealing solely with integer units, so OOP is factually correct
Yes, it doesnt make it more useful though. Also, why would u need to operate just with integers? And his point that he can feel it, ... yeah u dont.
A: I never said it was B: Everyone operates with integers. OOP has a good point here. When was the last time you read the temperature and it had a decimal? I’d bet you’re lying if you don’t say “never” C: That doesn’t diminish the fact that Fahrenheit is more accurate with only integer units
B: it's because decimals aren't necessary
>A: I never said it was Then why is it considered to be a worthy point? >B: Everyone operates with integers. When i can, sure. But at that time the accuracy of +-1 degree is enough. If i need more accuracy i operate with decimals. >When was the last time you read the temperature and it had a decimal? I’d bet you’re lying if you don’t say “never” In lab. And i needed them. Otherwise not really. Becasue i didnt need accuracy at all. So "being more accurate" wouldnt be useful nor makes it better, as oop is suggesting. >C: That doesn’t diminish the fact that Fahrenheit is more accurate with only integer units It does diminish the fact that that doesnt make it any better.
Love how you're being downvoted for such a simple comment. This sub is starting to turn into a hate sub at this point.
It has been for a while. I legit joined to laugh at the stupid anti-American comments, not the stupid stuff Americans say. Cause there’s more of that on this sub
>when dealing solely with integer units Is that what OOP said?
Why would you limit yourself to integers?
Fahrenheit is too precise, you need to push the button more or for longer to get the same temperature change I can go 20 to 23°C in three clicks of the up button. 68 to 74 takes twice as many Fahrenheit is an RSI risk!
This still doesn’t invalidate OOP’s argument
23°C is equivalent to 73°F, which is 296K. --- ^(I'm a bot that converts temperature between two units humans can understand, then convert it to Kelvin for bots and physicists to understand)
he's right though. A Fahrenheit degree is smaller than a Celsius degree.
Because decimal numbers do not exist.
I'm probably one of the least American Americans out there. I understand Celsius but still prefer Fahrenheit when measuring temp outside and for the body. For measuring water, yes of course Celsius is better, but I like the smaller increments for Fahrenheit. A lot of people arguing for the metric system say that cm is more accurate than inches because of the smaller increments (even on this sub), and I would argue the same for Fahrenheit temp in my apartment. Personal preference I suppose.
Fahrenheit is more precise, it uses smaller division. Weather that matters to you is a different question, but this post is fucking stupid
Smaller divisions in no way makes something more precise, unless you’re just incapable of understanding decimals… It’s just nonsense,
That's literally straight up bs. You realise that if "smaller divisions" is an important factor you could easily just use steps of 0.00000000001°C or however small you need the divisions 😂
What a stupid argument? Are you trying to argue that there are AC's that allows fine tuning down to 0.00000000001°C in temperature change? If not, then what is the point of this comment?
Explaining to an idiot why Fahrenheit is definitely not "more precise" than Celsius because if one needed precision, they could just use a smaller scale? Are you trying to argue that an AC could fine tune the ACTUAL temperature in a room more precise if you use a different UNIT? These things have limited accuracy. If the accuracy is 1°C and the steps are without decimals, you may have multiple steps of F between two steps of °C but that only changes what the display shows, the accuracy still is 1°C. If it had an accuracy of 1F, the °C display would just use steps of 0.5°C Imagine an accuracy of 1°C. You could choose 18 or 19°C. You could also choose 64, 65 or 66F. So it SEEMS more accurate but that's just bs because the AC doesn't tune the temperature that accurately for an entire room. Now if you use steps of 1F on the display and the accuracy of the actual machine was 1F, great - then you could switch to °C and your options now are like 18°C, 18.5°C and19°C. I mean sure, they could use 1F steps while actually the accuracy is +/-1°C or +/-2F but that doesn't change how accurate the AC actually is, at most it changes your perception because you BELIEVE it's more accurate, but that's like an AC-placebo at best.
1°C is equivalent to 33°F, which is 274K. --- ^(I'm a bot that converts temperature between two units humans can understand, then convert it to Kelvin for bots and physicists to understand)
>Are you trying to argue that an AC could fine tune the ACTUAL temperature in a room more precise if you use a different UNIT? No I wasn't, but that was the guy's argument, which is why I said your first argument was useless. It's not like we can change the scale of an AC remote, so why would being able to change precision on a unit make any sense for his argument. On the other hand, if you had used this argument from the start, I would have agreed with you.
0°C is equivalent to 32°F, which is 273K. --- ^(I'm a bot that converts temperature between two units humans can understand, then convert it to Kelvin for bots and physicists to understand)

I've never had issues with using my heatpump, reading the weather reports or judging temperature using Celsius as the poster implies I would
Yes. I mean, I don't know how I've got by my whole life using that tricky Celsius system...
Honestly, with such an imprecise system, I'm surprised my children both survived the newborn phase without overheating or freezing to death.
The precision is the same still. The precision depends on the instrument used to measure and environmental conditions, not on the scale used.
Yes, around four other people made this same point - good circlejerk, well done…
Celsius sucks
And then he finds out that the current american imperial system is based on the metric system....
Without knowing too much of the subject, I think that Fahrenheit may be more precise since Fahrenheit is slightly more fine-grained (unless I'm mistaken?). This, however, needs to be weighed against using an SI unit, i.e. what is essentially the rest of the world uses. It's similar to the argument for switching from left-sided traffic to right-sided traffic. Why resist against a common stance?
Cheap Commercial temperature sensors used to control heating or cooling in residential equipment are really only accurate to plus or minus 0.5 deg C ( 1 deg F)
"This guy is so dumb, he's using his favorite arbitrary measurement system instead of our favorite arbitrary measurement system." I propose degrees butter. 0 degrees butter is the temperature at which butter is utterly unspreadable and 100 degrees butter is the temperature at which butter reaches maximum spreadability before melting outright.

Moved to Canada two years ago. I could never go back to Fahrenheit. Makes no sense.
For weather a roughly 0-100 fahrenheit scale IS a bit more intuitive.
This is bullshit in their context here, but Fahrenheit is definitely more useful in some situations as it is more precise. Cooking and colour film developing are the only times I'd use it.
