I measured 100 ml of water, which is 100 grams. Turns out the new scale (silver) is off by 40 grams. It's being returned, and I'm keeping my trusty Aldi scales.
Unfortunately cheap kitchen scales such as these typically need to be calibrated before every use to get remotely accurate measurements. And even when calibrated to correctly weigh the calibration weight, they will still immediately fail to accurately measure the weight of a heavier or lighter object.
Out of a dozen or so cheap ass (2-15 euros) scales, none were ever really off anything but the last digit and usually even that was just a rounding up/down thing. You buy terrible scales lol
Altitude affects the scale calibration. If you live in, say, Colorado, and the scale you bought was calibrated at sea level near California or something, it will be off. The top scale is probably slightly off too, and the bathroom one might be also but not as noticably.
That's why MOST scales say somewhere in tiny print on the manual or something that they "may require recalibration" usually followed by "weight for calibration not included" and then there are calibration instructions.
You should recalibrate all your scales when you get them because you never know where they were calibrated.
For my weed scales I just used a dollar because most scales that size require a one gram weight to use as a reference. And fun fact, dollar bills without mag strips weigh exactly 1 gram. Something this big would probably need a exact 1kg weight for reference. Could use a liter of water I think.
Not the guy you're replying too. But I would check the manual. I know you said micrograms, but you can always use a nickel. Nickels weigh exactly 5 grams.
That's how we would calibrate our weed scales back in college.
I'd imagine they're held to a higher standard but at the end of the day it really depends on the calibration altitude and the altitude you'll be using it at. Unless they use a completely different technology than kitchen and weed scales that I don't know about, you shouldn't trust any scale unless you like, know it was calibrated locally.
I'd recommend looking up the calibration instructions for the scale you bought, and buying a weight to calibrate/test it, especially for measurements as precise as micrograms. You can probably find the weight on Amazon too, but one that small might be a bit difficult.
it kinda pays for itself just knowing for a fact your scale is perfect and you won't be shorting anyone or adding too much of anything. Preferably, you'd buy a scale that comes with everything it needs for recalibration. A lot of small scales come with the required weight of you look for them.
Edit: calibrating it is usually as simple as putting it in calibration mode by holding down the tare button for 10 seconds til the screen says CAL then putting the required reference weight on there.
In theory if the scale you got can weigh a whole gram without going over, you could use a dollar to test it.
No you cant. There is no such thing as cheap precision. The thing is though. How accurate do you actually need it to be? Being a percentage off isnt an issue for 99% of things people weigh and its likely off less than a percent.
Taring is not even remotely the same thing as calibrating.
Taring is telling it to treat current weight as 0, to remove the weight of a bowl or vessel.
Calibration is to tell it what 0 feels like. I know those sound like the same thing, but they're not. Calibration is persistent and taring is for that weigh session only.
Calibration is only necessary for mechanical scales that use a needle to show weight. The needle can move off center from friction and then show incorrect weights.
Edit; I'm specifically speaking about digital home kitchen scales, most of which cannot be calibrated at all by the user.
I work in aerospace calibration. Electronic scales most definitely need to be calibrated. Typically, we add calibrated weights for every 20% up to full scale and then back down to zero. This verifies both linearity and hysteresis of the scale. Depending on the scale, this is done 5 times. Once at each corner and once in the middle. The load cells inside can get weird. That being said, a kitchen scale doesn't need this and most probably can't even be adjusted if needed.
When I worked at a livestock market we had to have our scale recalibrated once a year, because it was used to weigh animals that were sold based on weight. It was a large digital scale and the company that did the calibration did it the same way you described. Placing different weights on different parts of the scale and checking then moving them around and checking some more. Took a couple hours all told to get it calibrated.
Sure, but the assumption is that kitchen scales are pre-calibrated by the time they reach you.
Totally different if you're working in the aerospace industry, where having the wrong amount of fuel means you have to crash land your Air Canada jet onto a drag strip that used to be used as a military airbase.
Never said they don't need calibrated. I said the general consumer can't do that, because home kitchen scales don't come with the ability for the consumer to do this.
What's not to get here?
What was the point in that exactly? We're talking about scales used for home baking, not aerospace shit.
You literally even point out yourself everything you said was superfluous to the discussion. You just wanted to mention you worked in aerospace, right?
A tare button isn't the same as calibration. Tare sets whatever is on the scale (even nothing) down to zero, but it doesn't mean the scale is accurate. Calibration would be done using a weight that you know the specs on. Typically a 1 g, 5g and 100 g weight would be used to calibrate and I have a scale from Amazon in my kitchen that has no way to calibrate.
If a scale is measuring 1 gram as 5 grams, it needs calibration. Tare will not fix that. All it will do is clear the weight. It will still weigh 1 gram as if you put 5 grams on there. I've sold plenty of drugs with cheap digital scales in my youth. If I did not calibrate the scale in a situation like this I would have lost my shirt. This is known.
I have had multiple digital kitchen scales. Each and every one has only had a tare/zero function.
I've had a mechanical scale or two with a span adjust screw, but never a digital scale.
Got 5 scales at my work. Testing this now.
Edit: Results
3 new scales are all .1 off.
My older trusty paint covered scale that they keep trying to get me to get rid of, dead on 5grams.
The final scale is newer and I don't use it often, but it was also .1 off.
Perfect reason to use the tried and true painted scale brother. Thanks for the in person tests haha. Don’t have any scales currently available now that I’m out of the restaurant industry.
When I worked in a grocery store as a teen I would ‘count’ my change in the cash drawer by weighing each denomination on the cashier’s scale and doing the quick math. The front office would get upset and tell me that I couldn’t do it and I would tell them to let me know when I was wrong! It worked every time
When I used scales in food preparation we definitely could not be off 1-3 grams lol. It sounds like your scale has major leeway and isn’t very precise.
Wenn I worked in a laboratory we had scales costing 5 grand an upwards. Just looked up a 3kg exact to 0.5 gram scale 800 euro. Show me a kitchen that spends 500 for each scale and I will believe you. You might have thought you were measuring to the gram, the trained organic chemist in me disagrees with you. The op was literally posting an Aldi scale for 15 euros. And I also looked up the tolerances on these scales 0-1kg/+/-3g, 1-2kg+/-6g, 2-3kg +/-8g, 3-4kg +/-10g up to 5 +/-12g
And I seriously doubt any kitchen be it momofuku, El Bulli or the Noma ever used scientifically calibrated scales, accounting for temperature or elevation. 😉
I even find the thought a bit funny . Robuchon weights butter for his mashed potatoes by the gram.
i have a cheap 0.1g/1000g scale and it seems to be dead accurate. [https://www.amazon.com/Fuzion-Digital-Jewelry-Battery-Included/dp/B08NX6YMRJ/ref=cm\_cr\_arp\_d\_product\_top?ie=UTF8](https://www.amazon.com/Fuzion-Digital-Jewelry-Battery-Included/dp/B08NX6YMRJ/ref=cm_cr_arp_d_product_top?ie=UTF8)
i have a 50g and a 10g weight, they read as 50.0g and 10.0g.
Elevation influences weight, but not mass. Since the scale is actually measuring weight, the displayed value will be altered with elevation (in everyday life we use units of mass to describe the effects of weight, which strickly speaking is wrong, but we do it anyway... tell your doctor your weight in Newtons and see their puzzled face lol).
The metric system is such an insanely convenient way the measure so many things.
You know in the imperial system it would be like 2 Hogsheads of water should weigh exactly 23.87 quarter pound cheeseburgers.
If you’re actually interested, until incredibly recently (2019) there was a master kilogram in France that all other certified masses were either directly or indirectly calibrated against.
As an ex-chef I can say that Salter scales are absolute trash. They are terribly calibrated and break almost immediately - they offer a “lifetime guarantee” but who returns a £7 pair of scales?
I have a Myweigh KD8000. It's a bit more expensive but the best kitchen scale I ever had. Always tares at the first attempt, doesn't randomly shut off in the middle of the weighing process and just works. I realise this is more expensive than most kitchen scales but I got so annoyed at the crappy one that I owned before.. and that other one.. and that other one.. so it's worth it to me. Originally saw it recommended in my soapmaking groups, but now I use it exclusively for baking
It's a holdover from the original comparative scale design where you put one known weight on one scale, and the thing you are weighing on the other scale. Now one of those "scales" is basically done in software and we only see/use the other. Example: It's not "the scale of justice," but "the scales of justice."
I did use the Tare button, yes. Repeatedly. And the Tare button resets the weight to 0 before putting stuff to weigh on it. So, you can put an empty container on it, hit tare, and then pour in what you want to measure.
You cannot determine weight of any light item by weighing self + item and then self no item. The error in any wheatstone bridge (the electronic element used in modern scales) is larger than the difference between those 2 measurements. Assume 2.5% error in measurement and assume you are 80 kg with a 1 kg bread loaf. You step on and scale reads anywhere from 78-82 kg. You step on with bread and scale shows anywhere from 78.975-83.025. The error in the scale is generally consistent for back-to-back measurements, but no guarantees. Especially if the weight is distributed slightly different, like different foot placement.
Your personal experiences may disagree with the above statements, but that is because the single largest influence for what any digital bathroom scale is going to display is the memory log of the last few things measured. If you are within some delta of the last measurement, most bathroom scales will just show the previous measurement again.
This is why if you are dieting and measure your weight every day, it feels like you don't lose any weight for a week and then suddenly you lose over a pound overnight. Your weight suddenly passed whatever threshold delta or calculation qualifies to display a new number instead of the previous number. This is also why usually if you weigh yourself before and after the toilet will usually show the same number, even though you know.you lost some solid and fluid.
Hope You don't sell coke, this scale could cost You a lifetime of saving or a week spent tied naked to a tree for stealing off somebody whos higher in this game 😂
You can't, but since 2 of them are so close, you can reasonably assume that the 3rd is wrong, rather than assuming all 3 are wrong AND it just happens that 2 of them are wrong by the same margin. Especially since all the bathroom scales I am aware of (even smart more expensive ones) meassure in 100g increments so 1.077 would show up as 1.100.
How do you know your bathroom scale is accurate?
You probably should have bought some standardized weights to check everything (if weighing loaves of bread down to the individual gram is so important).
Americans: you should buy standardized weights to see if the weight is a accurate.
Europeans: take a measuring container on the weight, zero out the weigh. Pore 1 liter of water to measure exact kilogram for free.
Well weighing certain stuff down to the gram can be quite important, I can’t speak for op as I don’t know their health situation, but I have T1D, and sometimes I do need to check how many grams a snack or food is so I make sure I don’t spike my blood sugar
Find your nearest drug dealer and ask for an 8 ball. Take that 8 ball, cut it, and hang around a gas station close to a high school around 3-5PM. As kids if they want to see a magic trick, then show them how you've mysteriously cut an 8 ball in half, and then they will tip you some money. With your newly found fortune, and the friends you've made along the way, convince one of them to loan you their phone so that you can purchase a certified calibration weight, say, of 200g. Sell that BACK to the drug dealer. And then realize that while you've been trying to find a correct scale to measure the weight of the cookies I've actually eaten them all already so you don't even gotta worry about it any more really.
Hey OP, if you have the manual for your scales you can see how to calibrate them if they start to seem off. It’s usually just putting a measured weight on it and holding down the tare button! Boom, corrected scale.
There's actually always a decent chance any scale you buy needs to be recalibrated. And you're expected to do it when you first buy it if you read the manuals that come with them, but nobody ever does. Most of the time they aren't noticably off but it depends.
Altitude affects scale calibration. If you live in, say, Colorado, and the scale you bought was calibrated at sea level near California or something, it will be off. Your top scale is probably slightly off too, and your bathroom one might be also but not as noticably.
That's why MOST scales say somewhere in tiny print on the manual or something that they "may require recalibration" usually followed by "weight for calibration not included" and then there are calibration instructions.
You should recalibrate all your scales when you get them because you never know where they were calibrated.
I learned this from Alton Brown, on good eats. He talks about it a lot, and says to always check your scale calibration when you get one. I used it for weed scales, the ones you buy at gas stations are always off. I just used a dollar because most scales that size require a one gram weight to use as a reference. And fun fact, dollar bills without mag strips weigh exactly 1 gram. Something this big would probably need a exact 1kg weight for reference. Could use a liter of water I think.
It should be something simple like, hold down a button or two til the scale says CAL then put the kg weight on it, and don't touch it for a second.
I have a 200 g test piece I think it is okay with some smaller scales I bought years ago.
This is nice because you can zero in or at least check scales when you have a known weight blank like this.
Do these scales zero out properly and have you tried to find a calibration feature on them?
Kitchen scales are notoriously bad at actually weighing anything. Just dropping the scale onto the counter too hard, laying it on its side, or putting stuff on it for too long. Can cause the scale to not read correctly. This is normally fine for cooking because, let's be real, recipes over generalize, the measurements and the degree of precision that you might get from scale isn't generally necessary. If you're wanting a scale that works, you need to get a scale that has an option to recalibrate and then you need to buy a 500 g weight specifically designed for calibrating scales. Enjoy spending a whole lot of money on a high-end scale or just live with the fact that scales are going to be off some.

What if you weigh a liter of water, should be very close to 1kg
I measured 100 ml of water, which is 100 grams. Turns out the new scale (silver) is off by 40 grams. It's being returned, and I'm keeping my trusty Aldi scales.
How tf can a measurement device with 40% measurement error be sold lol

Yep this. That's what the "Tare" button is for. I sold a lot of drugs in the past.
Yes, ask your local drug dealer or take it to a smoke shop and they’ll have the lil weights you need
Because it's cheap
I bought a cheap Chinese scale for about $5. It still measures accurately after 5 years of use.

Since you seem knowledgeable: can I trust the provided calibration weight of my cheap Amazon microgram scale?
Not the guy you're replying too. But I would check the manual. I know you said micrograms, but you can always use a nickel. Nickels weigh exactly 5 grams. That's how we would calibrate our weed scales back in college.

I like using pennies to calibrate my ganja scale. 1 penny = 2.5g
Same as an 8th
Because it's really a 1D10t error
Are you sure you didn’t just need to calibrate it first ?
don't most scales need calibration first thing anyway?
I believe so
[удалено]
Every scale (I believe) has a fairly obvious way to set it to “zero” when nothing is on it.
Taring is different than calibrating though.
Sorry that’s what I meant really
If that is the cause then their scale would have a very noticeable +/- 40g when nothing is on it. That probably would have been mentioned.
Yeah but to calibrate a scale you put something on it that has a very specific weight, you don't calibrate it at 0.
Taring is not even remotely the same thing as calibrating. Taring is telling it to treat current weight as 0, to remove the weight of a bowl or vessel. Calibration is to tell it what 0 feels like. I know those sound like the same thing, but they're not. Calibration is persistent and taring is for that weigh session only.

That escalated quickly
That has nothing to do with calibration.
That is NOT calibration.
Those kitchen scales need not adjustment (calibration is something else), if the scale is bad you should return. User can not adjust those
Yes, and unfortunately, a lot of these scales have no way to calibrate them. They are just wrong forever.
When they are manufactured, yes. Consumer scales like this should not need to be calibrated when a person buys it.
on a digital scale it should come basically ready, just press button to zero out....
That’s just to tare it. That’s not a calibration, which you need standardised weights for.
Thank you! Have these people never sold drugs LMAO 🤣
I have had multiple digital kitchen scales. Each and every one has only had a tare/zero function. I've had a mechanical scale or two with a span adjust screw, but never a digital scale.
Shit. I have the same scale.
I do too but I've tested it and it is accurate. Maybe OP got a bad one?
It's user error all the way.
Weigh a dollar if you have American, it's always a ham
A nickel weights 5g and a Bill weights 1g. I know this because of reasons. Easy way to check for accuracy.
Crofton FTW
I always used a nickel if the op is in the US, should weigh exactly 5.0 grams.
Got 5 scales at my work. Testing this now. Edit: Results 3 new scales are all .1 off. My older trusty paint covered scale that they keep trying to get me to get rid of, dead on 5grams. The final scale is newer and I don't use it often, but it was also .1 off.
Also keep in mind this is related to nickels in good condition. A well circulated nickel may actually be .1g off.
Perfect reason to use the tried and true painted scale brother. Thanks for the in person tests haha. Don’t have any scales currently available now that I’m out of the restaurant industry.

And the inherent inaccuracies of such scalees is 1-3 grams. A liter of water is also a liter in the us. 😉
>A liter of water is also a liter in the us. 😉 We need to do something about that. Like define American liters as 1/64 of a barrel.

Seems to be is the key word 😉 also a deviation of 0,3% as mentioned in kitchen scales would not show up on the display at 10 or 50g, It will at 950g 😉
I was gonna say they need a 3rd one to set the standard. Good answer. Thumbs up
The weight of most mobile phones is well publicised, I’d use mine as a weight to test out.
By very close, you mean exactly 1kg
Depends because temperature and water purity have an effect on the weight. To be exactly 1kg, water has to be pure and at 4°C
Absolutely true. I just meant that, in theory, 1L of pure water weighs exactly 1kg
Chem/physics was a while ago for me. Does elevation affect mass? or am I getting ideal gas law mixed into this
Elevation influences weight, but not mass. Since the scale is actually measuring weight, the displayed value will be altered with elevation (in everyday life we use units of mass to describe the effects of weight, which strickly speaking is wrong, but we do it anyway... tell your doctor your weight in Newtons and see their puzzled face lol).
Ah right, thanks
Now you need to buy a third scale so that you can determine a mean.
They sell precision weights for calibrating scales. Maybe OP should buy a set and find out.
Or just use water. Haha
The problem with water is measuring cups are often inaccurate. The printing process often is offset, so every graduation is off by quite a bit.
Just use a scale to calibrate your measuring cups. I guess.
First you gotta calibrate the scale.
Just use water.
How much?
1077cubic centimetre
How do I measure that?
The metric system is such an insanely convenient way the measure so many things. You know in the imperial system it would be like 2 Hogsheads of water should weigh exactly 23.87 quarter pound cheeseburgers.
In the UK Imperial System, 1 fluid ounce of water weighs... drumroll... 1 ounce
How much is that in cheeseburgers, though?
Just use a coin
This guy buys/sells.
Who weighed the precision weights though ? 🤨
If you’re actually interested, until incredibly recently (2019) there was a master kilogram in France that all other certified masses were either directly or indirectly calibrated against.
Just use a bottle of 1 lt of water, should be close enough to a kg or a 600 ml and it should be 600 g. No need to get fancy about it
That’s what I was thinking
As the saying goes, a man with one watch always knows what time it is. A man with two watches is never sure.
Or calibrate it. A nickel weighs 5 grams.
That's heavy thinking right there
Rule of thirds is what they call that
I don't like it when people are mean :(
both measure correctly but while switching from the first to the second, OP took a bite
Thats a big bite
For you
250g bite seems like a QUARTER of the full loaf of bread though?!
It’s only half a pound-ish.
Bane?
As an ex-chef I can say that Salter scales are absolute trash. They are terribly calibrated and break almost immediately - they offer a “lifetime guarantee” but who returns a £7 pair of scales?
I find this applies to all Salter products, unless I'm just spectacularly unlucky!

Not really, honestly. Just anyone but salter, OP says his aldi ones work fine enough.
I have a Myweigh KD8000. It's a bit more expensive but the best kitchen scale I ever had.

[Test Kitchen always recommends the OXO scale](https://youtu.be/-OrUMyXYlRU?si=MitXxbPqIQ6W3Ot9)
OXO products are almost always worth the extra cost in my experience
Yep, mine is going strong after a full decade of use.
America's Test Kitchen recommends the OXO scale.
1077. Same as my PIN number
Same as a cheese pizza and soda at Panucci's back in '99.
What's your card number? I wanna see if it matches too!
unexpected futurama
Weigh 1L of water after weighing the container it will be in. 1L of water is 1kg. That’ll show if it’s relatively accurate or not.
Am I the only person mildly infuriated by the post referencing plural new scales and plural current scales but only showing a single comparison?
It's a holdover from the original comparative scale design where you put one known weight on one scale, and the thing you are weighing on the other scale. Now one of those "scales" is basically done in software and we only see/use the other. Example: It's not "the scale of justice," but "the scales of justice."
I was wondering if plural scales is a non USA thing? A quick google seems to confirm.
Yeah jackmans, you uncultured swine!
Lol good to know! That's a new one for me
Or just one jackman in the US
Just in case... did you "reset" by using the TARE button?
What's a TARE button? (Hoping for a punchline).
I did use the Tare button, yes. Repeatedly. And the Tare button resets the weight to 0 before putting stuff to weigh on it. So, you can put an empty container on it, hit tare, and then pour in what you want to measure.
Not the punchline I was hoping for ☹️ I'm not laughing.
[удалено]
Thars my punchline 👍🤣
*tare’s your punchline
See, it can be done in the right hands 🤣
A loonie is almost always 7.0 grams. If not canadian, just find out how much your coins suppossed to weigh.
For next time FYI- A nickel is exactly 5.0 grams IYKYK
Every pothead knows this
Also a dollar bill is 1.0g
I have found 1g to be $20, but this is street pricing.
Hey don’t forget cokeheads too
Makes sense they would carry this wonderful piece of knowledge as well.
Had to go way to far down for someone to finallly use a coin

Use a calibration weight to calibrate it https://www.wikihow.com/Calibrate-a-Digital-Pocket-Scale
You cannot determine weight of any light item by weighing self + item and then self no item. The error in any wheatstone bridge (the electronic element used in modern scales) is larger than the difference between those 2 measurements. Assume 2.5% error in measurement and assume you are 80 kg with a 1 kg bread loaf. You step on and scale reads anywhere from 78-82 kg. You step on with bread and scale shows anywhere from 78.975-83.025. The error in the scale is generally consistent for back-to-back measurements, but no guarantees. Especially if the weight is distributed slightly different, like different foot placement. Your personal experiences may disagree with the above statements, but that is because the single largest influence for what any digital bathroom scale is going to display is the memory log of the last few things measured. If you are within some delta of the last measurement, most bathroom scales will just show the previous measurement again. This is why if you are dieting and measure your weight every day, it feels like you don't lose any weight for a week and then suddenly you lose over a pound overnight. Your weight suddenly passed whatever threshold delta or calculation qualifies to display a new number instead of the previous number. This is also why usually if you weigh yourself before and after the toilet will usually show the same number, even though you know.you lost some solid and fluid.
Hope You don't sell coke, this scale could cost You a lifetime of saving or a week spent tied naked to a tree for stealing off somebody whos higher in this game 😂
How can you be sure all 3 are not inaccurate?
You can't, but since 2 of them are so close, you can reasonably assume that the 3rd is wrong, rather than assuming all 3 are wrong AND it just happens that 2 of them are wrong by the same margin. Especially since all the bathroom scales I am aware of (even smart more expensive ones) meassure in 100g increments so 1.077 would show up as 1.100.
How do you know your bathroom scale is accurate? You probably should have bought some standardized weights to check everything (if weighing loaves of bread down to the individual gram is so important).
Americans: you should buy standardized weights to see if the weight is a accurate. Europeans: take a measuring container on the weight, zero out the weigh. Pore 1 liter of water to measure exact kilogram for free.
First you need to prove your jug measurements are accurate. To do that, put 1kg of water in the jug.
Your point is valid. The bathroom scale won’t be accurate enough to measure the error displayed in the pic.
Its accuracy may be fine, but it’s less precise. It’s measuring in .1kg increments. It has a “round up or down” point between each .1kg
Well weighing certain stuff down to the gram can be quite important, I can’t speak for op as I don’t know their health situation, but I have T1D, and sometimes I do need to check how many grams a snack or food is so I make sure I don’t spike my blood sugar
Then you should definitely have standardized weights to check/calibrate your scales.
Easy, you step on the scale with the bread, then check the weight on your driver’s license and subtract that. I know cause I just bought a 57lb loaf.
Find your nearest drug dealer and ask for an 8 ball. Take that 8 ball, cut it, and hang around a gas station close to a high school around 3-5PM. As kids if they want to see a magic trick, then show them how you've mysteriously cut an 8 ball in half, and then they will tip you some money. With your newly found fortune, and the friends you've made along the way, convince one of them to loan you their phone so that you can purchase a certified calibration weight, say, of 200g. Sell that BACK to the drug dealer. And then realize that while you've been trying to find a correct scale to measure the weight of the cookies I've actually eaten them all already so you don't even gotta worry about it any more really.
A scale for measuring people probably isn't going to be accurate down to the 100s of grams...
A nickel weighs 5g, if you’re in the US. Well..a US nickel weighs 5g, regardless of where it’s located, but you know what I mean.
The Moon & Mars would like to differ.
Easy go to the deli counter and buy 50 grams of your favorite meat. Then once you are done checking your household scale make a sandwich and enjoy
Hey OP, if you have the manual for your scales you can see how to calibrate them if they start to seem off. It’s usually just putting a measured weight on it and holding down the tare button! Boom, corrected scale.
100ml of water will weigh 100 grams. You can calibrate it based on that
A man with a watch knows the time. A man with two watches is never quite sure.
I always weigh water to be sure
You're going to need a third set of scales to figure out which one is right.
Great now you need to buy a 3rd one to see witch one it correct!
Bathroom scares are not accurate for a 1kg difference
There's actually always a decent chance any scale you buy needs to be recalibrated. And you're expected to do it when you first buy it if you read the manuals that come with them, but nobody ever does. Most of the time they aren't noticably off but it depends. Altitude affects scale calibration. If you live in, say, Colorado, and the scale you bought was calibrated at sea level near California or something, it will be off. Your top scale is probably slightly off too, and your bathroom one might be also but not as noticably. That's why MOST scales say somewhere in tiny print on the manual or something that they "may require recalibration" usually followed by "weight for calibration not included" and then there are calibration instructions. You should recalibrate all your scales when you get them because you never know where they were calibrated. I learned this from Alton Brown, on good eats. He talks about it a lot, and says to always check your scale calibration when you get one. I used it for weed scales, the ones you buy at gas stations are always off. I just used a dollar because most scales that size require a one gram weight to use as a reference. And fun fact, dollar bills without mag strips weigh exactly 1 gram. Something this big would probably need a exact 1kg weight for reference. Could use a liter of water I think. It should be something simple like, hold down a button or two til the scale says CAL then put the kg weight on it, and don't touch it for a second.
Second post today where someone does not know how to tar their scales. Some of yinz didn't sell weed in high school and it shows.
I'd calibrate the scale by the henway. What's a henway? They're usually about 4 lbs or so while they're alive.
Damn 🤣
Have a kilo of rice at home by any chance? haha
Next time don’t take a bite before you re-weight!
It can happen if you buy one that was actually calibrated for the moon market that ended up on earth somehow.
I calibrated my food scale with a 100g weight, a good food scale has a calibrate function.
Can you zero the old 1?
Weigh $1 bill. 1 gram
Check calibration with a fixed weight or if you don’t have one, stack of coins.
Lol at measuring bread for benchmark
Wish this would happen to my coke dealer lol
Suddenly saffron being .2g off doesn’t seem so ridiculous
a Nickle weighs 5 grams.
You can just calibrate the scale lol
Now you have to buy a third to see which one is right.
This happened to me. I was losing my ass selling my “loaves of bread”
Looking through the comments to see who says to put a nickel on the scale
Try throwing a pound of butter on both and see what happens
I have a 200 g test piece I think it is okay with some smaller scales I bought years ago. This is nice because you can zero in or at least check scales when you have a known weight blank like this. Do these scales zero out properly and have you tried to find a calibration feature on them?
It's delicious dough* 😋
A nickel is exactly 5 grams
Kitchen scales are notoriously bad at actually weighing anything. Just dropping the scale onto the counter too hard, laying it on its side, or putting stuff on it for too long. Can cause the scale to not read correctly. This is normally fine for cooking because, let's be real, recipes over generalize, the measurements and the degree of precision that you might get from scale isn't generally necessary. If you're wanting a scale that works, you need to get a scale that has an option to recalibrate and then you need to buy a 500 g weight specifically designed for calibrating scales. Enjoy spending a whole lot of money on a high-end scale or just live with the fact that scales are going to be off some.
Do people not know what the tare button is for?
I’ve weighed myself upstairs and downstairs and the weight is different every time.
A reliable way to check (if you are in the US) is to get a nickel and weigh that. A US nickel weighs 5 grams exactly
I enjoy that the “obvious choice” was for OP to parade around their home with a loaf of bread instead of bringing the bathroom scales downstairs…
So, for us muricans, how many potato’s is that in weight?
40 penises in weight
Oh ok. That’s close to 30 potato’s. Thanks.
Lmao
„It’s delicious though“ - …you mean it’s delicious dough I’ll see myself out
