The converter opens in the Weight category with pounds as the starting unit and kilograms as the target. Changing the pound value moves the kilogram result, the formula and the table of other weight units together.
Kilograms are pounds multiplied by 0.45359237, an exact factor, so 200 lb is about 90.72 kg. If a form wants kilograms to a set number of decimals, round only the final figure, so earlier rounding does not add error. For the reverse, see kg to lbs.

Questions
How many kilograms is 150 lb?

What if my weight is in stone and pounds?
Turn the stone part into pounds first, since one stone is 14 lb. Add the remaining pounds, then convert the total here. For example, 10 stone 4 lb is 144 lb, about 65.32 kg.
How do I convert miles to kilometres?
Multiply the miles by 1.609344. A mile is exactly 1,609.344 metres, so 10 miles is 16.09344 km.
Why are US and UK gallons different?
A US gallon is 3.785411784 litres and a UK (imperial) gallon is 4.54609 litres. The UK gallon is about 20% bigger, so the same volume is a smaller number of UK gallons.
What is the difference between KB and KiB?
A kilobyte (KB) is 1,000 bytes and a kibibyte (KiB) is 1,024 bytes. Some operating systems show binary sizes with the decimal label, so a 1 TB drive can be reported as about 931 GB.
Is a cup 236.6 ml or 240 ml?
Both are used. The US customary cup is 236.6 ml, or 8 US fluid ounces. Nutrition labels use a 240 ml cup, which is about 1.4% larger, so check which one a recipe means.
