Both pounds (lbs) and kilograms (kg) are used to measure weight or mass. Pounds are an imperial unit most often used in America, while kilograms are a metric unit commonly used in European countries. With 1 pound equaling 0.454 kilograms and 1 kilogram equaling 2.2046 pounds, there are multiple ways to convert between the two units. Read on for step-by-step instructions.
Things You Should Know
- Divide the number of pounds (lbs) by 2.2046 to get the amount in kilograms (kg).
- Multiply the number of kilograms (kg) by 2.2046 to get the amount in pounds (lbs).
- Round your answer to the nearest hundredths place for a more concise and accurate result.
Steps
-
Divide the number of pounds by 2.2046 to use the standard equation. For example, if you want to convert 50 pounds to kilograms, divide 50 by 2.2046, which is equal to 22.67985 kg. To convert 200 pounds to kilograms, divide 200 by 2.2046, which is equal to 90.71940 kg.[1]
-
Multiply the number of pounds by 0.454 as an alternative. If you find multiplication easier to do in your head than division, you can use a different conversion factor to convert pounds to kilograms. For instance, to convert 100 pounds to kilograms, multiply 100 by 0.454, which is 45.4 kg.[2]Advertisement
-
Round your answer to the hundredths place. In most instances, you won’t need to use more than 3 numbers after the decimal point. So, if your answer is 22.67985, round that to 22.68. As another example, round 90.71940 to 90.72.[3]
- Avoid rounding the number of pounds before you convert them to kilograms.
-
Multiply the number of kilograms by 2.2046 to use the traditional formula. For instance, to convert 75 kilograms to pounds, multiply 75 by 2.2046, which is 165.345 lbs. To convert 350 kilograms to pounds, multiply 350 by 2.2046, which is 771.61 lbs.[4]
-
Divide the number of kilograms by 0.454 if you find that easier. If you prefer, you can use division to convert kilograms to pounds. For example, if you want to convert 25 kilograms to pounds, divide 25 by 0.454, which is 55.066 lbs. Or, divide 500 kilograms by 0.454 to get 1,101.321 lbs.[5]
-
Remember that there will be more pounds than kilograms. Because 1 kilogram equals 2.2046 pounds, there will always be more pounds than kilograms once you do the conversion. Keep this in mind and recheck your calculations if you ever have more kilograms than pounds.[6]
- For instance, 30 kilograms equals 66.138 pounds, and 1,000 kilograms equals 2,204.6 pounds. In both examples, there are more pounds than kilograms.

- Just something to note, I happen to know a few nurses and they never use the "in your head" method for approximate results. If you're doing something important, like measuring medication doses, every single digit matters!
