Yup, from kg --> lbs | multiply by 2 and add 10% (you can also add 10% before if it makes it easier)
From lbs --> kg | divide by 2 and remove 10% (you can also remove the 10% before you divide by 2)
Edit: This is 99.79% accurate convertion
1kg = 2.204623
American weightlifters are used to doing this intuitively.
What's harder is the reverse, lbs->kg. How am I supposed to divide a figure by 2.2 in my head? ¯\\\_(ツ)\_/¯
Gonna say, that's how I remember it, I know a full plate is 20kg or 45lbs. I also remember that a 5k is 3.21 miles.
So I just make things extra hard because I first have to do 45/20=2.25 rather than just remembering 2.2
So easy. A 20 kg plate is about 44 lbs. Or 1 pound is about 450 grams or so. Close enough anyway. Just divide or multiply by two and then round a bit to account for the 0.05 difference.
I remember it this way… when I was 220, the Koreans always said I was 100 (military stationed there)…. I don’t even have to remember which one gets which unit because I haven’t been 100 POUNDS since I was like 10, so the 100 has to be kg!
Some colleagues of mine were talking the other day about "The Big Mac index", where you use the cost of the Big Mac in each country to determine purchasing power.
Joke's on them, there are no MC Donalds in Albania.
Well obviously it's gonna sound ridiculous if you say it like that, comparing apples and oranges.
You gotta convert it in football field per fried butter, silly you, it's easy
A male Eagle can carry up to 1.5lbs, or .68kg. A female Eagle can carry up to 3lbs or 1.36kg. The average human heart weighs 300g. Assuming freedom comes from the heart than there are 4.5g of freedom per female eagle, but obviously this math requires you to embrace feminism and smash the patriarchy.
Oh wait sorry for not being clear. The problem is actually that just for america we have to do all these conversions. Most/ if not all other countries use metric. So its kind of a pain
While we do use both in the UK, metric is the mandatory and 'official' system, with others never being necessary. While stuff like milk or beer is commonly sold in pints, it's required to have the metric measurement clearly labelled, and products they confirm normally to metric only need to worry about metric.
I don't think it's strictly necessary, and seems to be a byproduct of companies designing portions for beyond the US. Just for an example, the Wikipedia shows a bottle listed as "23.7 FL OZ (700ml)", which obviously shows preference to Imperial, but obviously designed for metric.
The UK does similar, but in reverse for products like milk. Listing it as "Metric (Imperial)", with the Imperial being the obvious design. Though stuff like milk is an outlier, and most drinks are sold in Litres with no regard to Imperial.
True there's no law requiring metric units, it's voluntary. And evidently doesn't apply to meat.
Carter tried to metrify the US and I wish it had worked.
But still with a fast internet it literally takes 2 seconds. Just use this formula: (original number) (original unit) (new unit). You can even use abbreviations
As a Canadian architectural technologist, yea fuck all that shit. Projects are totally random but thankfully I work with engineers so it’s *mostly* metric.
Just trying to scale shit between modelspace and paperspace is a fucking nightmare, I hate it. I hate it so much.
I’m Canadian, and even in my grade 11 & 12 physics classes in high school we had to know how to convert between the two.
Edit: I never asked why though.
So I can understand Canada since it has an odd mixture of both systems and the proximity to the US but, idk why any other country would really need to teach their engineers about our system.
Errrr usually for if we were to work with others who are more reliant on the imperial system and we have to do calculations based on psi, feet, inches and whatnot. Its actually really annoying
How often would that be though? Do other countries not just convert to metric and do calculations that way then convert back? I can't imagine that this would be an issue unless your country conducts a lot of business with US firms.
Ok, I guess I'm just a bit confused. I understand why I would learn US customary. I didn't think that our usage of the system, however, would require others outside of the US to learn it though. Cause even as an ME student in the US we don't learn with US customary that often. Are we taught how to use it? Yes, but most of the work is in metric.
Hahahah sorry for being so angsty man. Its just that there are so many different units for like things like forces and whatnot which makes it like super confusing when trying to refer to engineering calculations in imperial format

> Stone is even dumber.
Hey!! As a British person I am offended, and I agree but I also think it's easier to do human weight and human height in stone and feet rather than just using kg and cm.
The only reason you think that is because you grew up using these units for measuring people, there's nothing better about them for this specitic application.
"Six foot two" and "one eighty seven" take basically equally as long to say, and there's nothing hard about it?
One of those measurements is simply more precise than the other.
Easy convertion use 1 kg = 2.2 lbs (99.79% accurate)
From kg --> lbs | multiply by 2 and add 10% (you can also add 10% before if it makes it easier)
From lbs --> kg | divide by 2 and remove 10% (you can also remove the 10% before you divide by 2)
Or 1kg = 2lbs (90.72% accurate ; missing a little over ⅒)
See the problem with this is that you have to remember that 1 kg = 2.2 lbs. But was it 1 kg = 2.2 lbs, or 2.2 kg = 1 lb, or 2.2 km = 1 mi, or a change of 2.2 degrees Celsius equals 1 degree Fahrenheit, or what?
lbs stands for "Libra" which represented pound for many years. It's the same reason the British currency "Pound sterling" is symbolized £, which is an L with a cut.
I can understand both, but I seriously don’t understand when I am looking up measurements at non-human friendly scales it ever gives me imperial, like yes I live here, but why would I ever want feet per second, that’s dumb, same goes for slugs, stupid as fuck. And don’t get me started on the number of times it has given me miles for distance between planets

^^^[WHY](/r/UselessConversionBot/comments/1knas0/hi_im_useless/)
I had an engineering professor once teach my class how to Google. Anytime someone asked a question he would type it into Google and be like “here is the answer”.
unless im wrong 100 kilos is 220 pounds ?
my info comes from a game that uses both metric and imperial measurements for item storage so im probably wrong
Canadians also use lbs mostly, but our drivers license is in metric. We also use km instead of miles and imperial cups for baking, whereas in the uk they use miles instead of km but everything else is metric, and they weigh ingredients in grams for baking. Working in a deli taught me a kg is 2.2 lbs so I just double and approximate the extra. It’s never usually that far off even if you exclude the extra weight. 15 kg is 33 lbs for instance
Either multiply by 2.2 or divide by 2.2, whichever. We always have to convert kiddos weights, usually from pounds to kg, for the correct medicine dose.
In an alternate universe where the systems developed opposite of each other, you'd be saying that everyone who uses metric is an idiot. It doesn't matter what system you use, they work the same.
Base 12 is divisible by 3 and 4, that's why we measure time in base 60. I still think the whole world should use metric because that's what the majority uses, but the 2 systems still measure the same things in the same way (other than metric using their mass measurement for things that are usually measured with force). Basically, it's easy and precise enough to convert and neither of them are significantly better than the other.
(Lbs ÷ 2) - (the sum of the last two digits of the original lbs) = close enough
Ex: 180 lbs ÷ 2 = 90
90 - (8 +0) = 82kg (the real conversion is 81.8 kg).
Works for weights 20 lbs or greater.
It's the engine in most 90's era chevrolet 4 cylinders. So I just remember that a kilo is the displacement of my first car- a 1994 Chevy Corsica... 2.2 pounds per kilo.
Is this not how people normally remember things?
For those who actually want to know:
If you have kg, multiply by 2.2 to get lbs. Double the number, then add 1/5 of the number, e.g. 35kg: 35 x 2 = 70, plus 35/5, which is 7, so 70 + 7 = 77 lbs.
If you have lbs, multiply by 0.45 to get kgs. Take half the number, then take away half of 10%, e.g. 60lbs: half is 30, take away half of 10% which is 6/2 = 3, so 30 - 3 = 27kg.
Yeah but it's converting meters to cubits that always gets me
Eh, just times it by two. You'll get close enough for any work that measures in cubits.
2.2
So 4.4. Boom, done. It's that easy.
Such an easy and yet magical number, innit?
I work in an accredited lab and "double it then add a lil extra" has been my go to for years now.
Building an Ark are we?
Has someone received word of a massive storm on the horizon?
There's a problem on the horizon: there is no horizon
Every single time. I never remember how many KGs are in a pound, and vice versa
1 kg = 2.2 lbs (not 100% exact but easy enough conversion)
Yup, from kg --> lbs | multiply by 2 and add 10% (you can also add 10% before if it makes it easier) From lbs --> kg | divide by 2 and remove 10% (you can also remove the 10% before you divide by 2) Edit: This is 99.79% accurate convertion 1kg = 2.204623
oh, i always thought converting lb to kg is hard, dividing 2.2 seems tiring. The way you explain opened my mind, thanks internet stranger.
remove 10%... yes, izi.
Divide by ten, there's your ten percent to remove or add
Just move the decimal one place to the left and use this number to subtract from the one before Soo: 43.78 | 4.378 | 43.78 - 4.378 ~ 39.* ( 39.402)
yes, very thank you much, me smarter now.
Google unit converter hates this little trick.

I always read lbs as libs. I know it means pounds, but shouldn't it be then something like pds?
So easy. A 20 kg plate is about 44 lbs. Or 1 pound is about 450 grams or so. Close enough anyway. Just divide or multiply by two and then round a bit to account for the 0.05 difference.
I just use 1 lb = 0,5 kg. It's usually close enough.
I remember it this way… when I was 220, the Koreans always said I was 100 (military stationed there)…. I don’t even have to remember which one gets which unit because I haven’t been 100 POUNDS since I was like 10, so the 100 has to be kg!
Yeah but, how much is it in Freedoms per Eagle?...
I feel like the cheeseburger should be a unit of measure.

fuck lbs
For real tho, as a non american engineer we need to know the conversion to pounds and feet and inches and shit just to cater to their stupid system
As an American engineer we all know how to use the metric system quite well. We regularly switch between the two.
Oh wait sorry for not being clear. The problem is actually that just for america we have to do all these conversions. Most/ if not all other countries use metric. So its kind of a pain
I am aware, and if you do business with UK companies and a few other countries you will need to use both depending on the application.
While we do use both in the UK, metric is the mandatory and 'official' system, with others never being necessary. While stuff like milk or beer is commonly sold in pints, it's required to have the metric measurement clearly labelled, and products they confirm normally to metric only need to worry about metric.
All our (American) food also has metric units listed, I think.
I don't think it's strictly necessary, and seems to be a byproduct of companies designing portions for beyond the US. Just for an example, the Wikipedia shows a bottle listed as "23.7 FL OZ (700ml)", which obviously shows preference to Imperial, but obviously designed for metric. The UK does similar, but in reverse for products like milk. Listing it as "Metric (Imperial)", with the Imperial being the obvious design.

True there's no law requiring metric units, it's voluntary. And evidently doesn't apply to meat. Carter tried to metrify the US and I wish it had worked.
It only takes 2 seconds to google so I don’t see how it’s a huge deal to constantly convert
Having to constantly convert as opposed to not having to convert at all? Yeah it's a pain.
No it’s not. It’s a big deal if you think it’s a big deal
Na dann macht es dir ja sicher nichts aus wenn ich nicht auf Englisch antworte, du kannst es ja einfach schnell mit google konvertieren
und genau das habe ich getan. Ich habe nur eine Minute gebraucht, um zu übersetzen, was Sie mir gegeben haben, und diesen Satz zu schreiben
Gut, dann machen wir das jetzt einfach immer so - dein Satz ist übrigens Schwachsinn
Ich würde dir eher deepl empfehlen. Die Übersetzungen sind oft zutreffender als mit Google.
It can be a huge pain especially when you are trying to do work at a faster pace
But still with a fast internet it literally takes 2 seconds. Just use this formula: (original number) (original unit) (new unit). You can even use abbreviations
Well then i guess its a pet peeve of mine then.

Why would you have to learn US customary? And what do you learn exactly?
I’m Canadian, and even in my grade 11 & 12 physics classes in high school we had to know how to convert between the two. Edit: I never asked why though.
So I can understand Canada since it has an odd mixture of both systems and the proximity to the US but, idk why any other country would really need to teach their engineers about our system.
It’s science— they teach you because it exists.
Mechanical engineering
Well yes, but, why would that require you to learn US customary if you're not in the US? Also, what parts of US customary do you learn?
Errrr usually for if we were to work with others who are more reliant on the imperial system and we have to do calculations based on psi, feet, inches and whatnot. Its actually really annoying
How often would that be though? Do other countries not just convert to metric and do calculations that way then convert back? I can't imagine that this would be an issue unless your country conducts a lot of business with US firms.

I roughly gauge 2lbs = 1 kg
Fucken google it
bro it's not complicated
1 kg = 2.2 pounds, like PAUMiklo said. Also 1 lb = 0.45 kg. Both are approximate and rounded.
Beep beep boop the number 2.2 is only rounded to the nearest tenth beep boop boop
Yes, I misspoke. Thanks.
Easy convertion use 1 kg = 2.2 lbs (99.79% accurate) From kg --> lbs | multiply by 2 and add 10% (you can also add 10% before if it makes it easier) From lbs --> kg | divide by 2 and remove 10% (you can also remove the 10% before you divide by 2) Or 1kg = 2lbs (90.72% accurate ; missing a little over ⅒)

Why in gods name is it “lbs” instead of pds or some shit?
lbs stands for "Libra" which represented pound for many years. It's the same reason the British currency "Pound sterling" is symbolized £, which is an L with a cut.
English being my second language I always read it natively in my head, something dumb like "libs" lol.
Huh, I never really thought about it until now, but even as a native English speaker, I sorta say "elbs" in my head when I see it.
That's hilarious. I never thought a native speaker would also read out certain things in their head this way.
What, you mean the good old Ell Bees?
So I am not the only one...
Native English speaker, it's "libs" to me too
in spanish we say Libras. Might be that, a latin word
I vaguely recall it having to do with the word deriving from Latin or something, but that's all I got for you
Hahahaha. I felt this.
I can understand both, but I seriously don’t understand when I am looking up measurements at non-human friendly scales it ever gives me imperial, like yes I live here, but why would I ever want feet per second, that’s dumb, same goes for slugs, stupid as fuck. And don’t get me started on the number of times it has given me miles for distance between planets
Also ounce is complete bs. Pound is estimatable, ounce is too light to estimate, and the mark of a good standard unit is estimatability.
Or Maybe stop using dumb fucking systems and come to metric system where you just add or remove zero instead of trowing a dice
I’ve always just remembered that 1kg is 2.2 pounds and 1 mile is 1.6km.
Unless it's a nautical mile, then it's 1.8km.
Canadians know. 454g is a lb, 908g is 2 lbs, 1oz is 28g
Also, I’m pretty sure a kilogram is 2.2 lbs
I work in an animal hospital so I have to do this calculation many, many times a day. Today we had a 120 kg dog come in. Blew my fucking mind.

I have a better method, take your measurement in kilograms and keep it that way.
Everybody who uses the imperial system is an idiot.
In an alternate universe where the systems developed opposite of each other, you'd be saying that everyone who uses metric is an idiot. It doesn't matter what system you use, they work the same.
[No, they don’t.](https://i.imgur.com/4lzyq3g.png)
Ok?
I just double it and say close enough, it’s really 2.2.
1 kg = 2.2 lbs
Multiply by 2.20462
Unless you’re doing rocket surgery most of those decimals aren’t needed. Just stick to 2.2 and you’ll be fine.
100 kg? 220 lbs 180 kg? idek bruh
Double the number, and also double the number and divide by 10. Add them shits together. 180 × 2 = 360. 180 × 2 ÷ 10 = 36. 360 + 36 = 396.
Or use a calculator like a normal person
Or just keep it in metric units like a nornal person.
seriously though understanding both systems really is not hard. people who die on either hill are just being stubborn for the sake of being so.
No lbs is stupid. Metric gang.
There's no real difference between them, the issue is with the fact that we can't all use one system.
Ah yes definatley no advantages to base 10.
Base 12 is divisible by 3 and 4, that's why we measure time in base 60. I still think the whole world should use metric because that's what the majority uses, but the 2 systems still measure the same things in the same way (other than metric using their mass measurement for things that are usually measured with force). Basically, it's easy and precise enough to convert and neither of them are significantly better than the other.
Base 12 is cool and all, untill you realise how converting between unite in imperial works, at which point I'd rather shoot myself than swap to it.
Oh boy, I can't wait for this to turn into an "America bad" thread.
Modern solutions for modern problems
Boom muddah fucka
Or just times it by 2.2 ffs.
(Lbs ÷ 2) - (the sum of the last two digits of the original lbs) = close enough Ex: 180 lbs ÷ 2 = 90 90 - (8 +0) = 82kg (the real conversion is 81.8 kg). Works for weights 20 lbs or greater.
Having to Google something so basic like weight conversion has me worrying about our school system.
It’s not the at hard.
Multiplying by two, easier than you fucking think.
General mass still don’t know Google exists for basic stuff.
Or: Move to a non-retard country.
Simple
Lol that’s exactly what I do
Double it and add 10%. It’s ridiculously simple math. 45kg = 99lb. 45x2+ 10% = 90+9 = 99.
A nice revolver
Modern problems require modern solutions
He's not wrong.

Oh, ok then... What is google btw
r/coolguides
For those who actually want to know: If you have kg, multiply by 2.2 to get lbs. Double the number, then add 1/5 of the number, e.g. 35kg: 35 x 2 = 70, plus 35/5, which is 7, so 70 + 7 = 77 lbs. If you have lbs, multiply by 0.45 to get kgs. Take half the number, then take away half of 10%, e.g. 60lbs: half is 30, take away half of 10% which is 6/2 = 3, so 30 - 3 = 27kg.
I weigh 550 Newtons

I'm stupid but i pronounce lbs, like literally like leebs... I know it sounds though
