There is a way to convert Lb to kilos in your head and here's how Take the Lb number divide by 2. Now take off the ones place of the answer. Take that number and subtract it from your divide by 2 answer. And you will have Kg. Example: 180lb / 2=90. 90-9=81 Kg. . Now if we do the math from this video on the same problem we have 81kg X2= 162lb. 162+16 =178. It's not perfect but to do it quickly in your head. This helps

[@DuskoDramicanin]

(180-(180/11))/2=(180-16)/2=164/2=82 82*2+(10% of 164)=180,4

It’s high time The States moved to using modern unit measurements like kilometre and kilogram instead of mile and pound (lb)

[@TestifySC]

As a former math and physics teacher, I’m on board with that. That said, it’s fairly unlikely to happen anytime soon, so it’s nice to have a quick and easy way to convert for those times when one needs to do so.

[@bigteddy66]

Well said, more confusing is when the older generation in the UK know that there 2240lb in a ton and the us use a different ton and also a different gallon.

Hi i want to know how to convert pounds to kilogram can you teach me the easy way

[@garys.8333]

and THAT, is how you teach kids and keep their interest. Thanks!

[@TestifySC]

You’re welcome, and thanks for the kind words!

[@ndeleonn]

@@TestifySCThis is a nice trick and worth memorizing. However, this is not how you teach kids because to them it is a mystery why it works. For example, once they memorize this trick ask a kid to convert meters to miles - they won’t have a clue. Learning conversions and math should not be a mystery.

The equivalent for converting pounds to kilograms is to divide by 2 and then subtract an eleventh (1/11) from it.

Why change from pounds to kilograms? I don't get it and here in America?

[@TestifySC]

In this video, we cover how to change from kilograms to pounds. As for changing from pounds to kilograms like you mentioned, there's not a good shortcut for that.

[@Azzywrld224]

Would this work with a small number like 2.082🌚

[@TestifySC]

Sure, it's just a bit more of a hassle to deal with the extra digits. If you're talking about 2.082 kg, I'd recommend treating it as 2 kg or even 2.1 kg. Using this method with 2.1 kg, you'd do 2.1 * 2 = 4.2 and then add .42 (10% of 4.2) to get 4.62 lb, which is very close to the actual answer of 4.59 lb (plus some more decimal places).

[@SusanRush-hy8dh]

11.7

[@idkwhattonamemyself1730]

Can you do one the other way around cuz all I see is arrogant Americans saying everything in pounds

[@TestifySC]

It's a good question, and it'd be nice to have a reverse shortcut as well, but due to the mathematical nature of things, there's not a great shortcut to go from pounds to kilograms. What typically happens is that you become very adept at converting kilos to pounds and in the process end up memorizing a lot of common conversions (usually due to sheer repetition - not because you're necessarily trying to do so). For example, you end up knowing that 85 kg is 187 lb and 90 kg is 198 lb, and thus if you end up needing to convert 195 lb to kg, you can pretty quickly estimate it as around 88-89 kg. Hope this helps!

[@Dean-bb4ss]

@@TestifySC I had the same question in mind, thanks for the clarification

[@TestifySC]

You’re very welcome.

[@dmaikibujin]

It's not quite as accurate, but it's certainly close enough for exercises on the fly without a calculator. Same principle in reverse: Take the pounds: 187 Divide it by 2 = 93.5 (In your head divide the 18 first - then the 7) Move the decimal to the left one place and subtract the number to the left of the decimal: 93.5 - 9 Total = 84.5 Real Total = 85 150 pounds / 2 = 75 - 7 = 68 Real Total = 68 116 pounds / 2 = 58 - 5 = 53 Real Total = 52.7

[@BelRusMikalai]

It’s time to get rid of pounds

[@TestifySC]

As a former high school math and physics teacher, I would be fine with that as the metric system makes far more sense. To be fair to pounds, however, it’s also fairly idiotic that the lifting world measures weight in kilograms as that’s not correct either. At least measuring weight in pounds is correct in the sense of units, even if it is a silly measuring system.

[@asiyabella2462]

Ok 10 pound how much kg

[@TestifySC]

4.5 kg. You can check that by applying the same process. Thus, 4.5×2 = 9, and then 10% of 9 is 0.9. So you now have which 9 + 0.9 = 9.9 pounds, so 4.5 kg is approximately 10 pounds.

[@Williamxmr]

@@isitsustainable820 this is wrong. And been proven over and over.

[@MuhammadTaha-nh7vs]

I think its 177 pounds.

[@TestifySC]

Are you talking about the 85 kg example? You’re close, but remember to add 17 (since 17 is 10% of 170), not 7. It’s 187 if you use the shortcut (or about 187.39 if you do a more precise conversion).
