Method 1Method 1 of 2:Pounds to Kilograms
- 1Divide 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]

- 3Remember that there will be more pounds than kilograms. Because 1 kilogram is equal to 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 pounds than kilograms.[6]
- For instance, 30 kilograms is equal to 66.138 pounds and 1,000 kilograms is equal to 2,204.6 pounds. In both examples, there are more pounds than kilograms.
Quick and easy pounds to kilograms conversion
If you’re just trying to convert pounds to kilograms for cooking or to know your own weight, there’s a handy rule of thumb you can use:
To get kilograms, divide by 2 then take off 1/10th of your answer
Eg 100 pounds… Divide by two = 50 Kg. Take off 1/10th = (50 – 5) = 45 Kg.
This is close to the genuine answer of 45.35923kg, and is a much easier sum to do in your head!
