Kg to Lbs: Kilograms to Pounds Converter
Kilograms, pounds, and stones and pounds together, for the values people look up most.
Enter a number.
This converts mass, not force. Kilograms and pounds both measure mass in everyday use, which is what a bathroom scale or a luggage scale reports. If you have a figure in pounds-force from a spec sheet, spring rating or test result, use the newtons to pounds converter instead.
The formula
kg = lb × 0.45359237 (exact)
The pound is defined as exactly 0.45359237 kilograms, so that factor is exact. The reverse figure, 2.2046226, is its reciprocal rounded to seven decimal places. Factors per the NIST Guide to the SI, Appendix B.

Mass and weight
Strictly, kilograms and pounds measure different things. The kilogram is a unit of mass, and the pound in everyday use is also a unit of mass, though pound-force is a unit of force. On Earth the distinction rarely matters for weighing yourself or your luggage, which is why the conversion above is treated as a straight ratio.
The two most common reasons to run this conversion are airline baggage allowances, usually posted in kilograms outside the United States, and gym plate weights, which come in both.
Common questions
What is 80 kg in pounds?
80 kilograms is 176.37 pounds, which is 12 stone 8.4 pounds. The pound is defined as exactly 0.45359237 kilograms, so the conversion is exact and only the display is rounded.
Is 1 kg equal to 2 lbs?
Close but not exact. One kilogram is 2.2046226 pounds, so doubling underestimates by roughly 10 percent.
What is the exact kg to lbs factor?
The definition runs the other way: one pound is exactly 0.45359237 kilograms. The kilogram-to-pound figure of 2.2046226 is the reciprocal, rounded.
What is 70 kg in stones and pounds?
70 kilograms is 154.32 pounds, which is 11 stone 2.3 pounds. A stone is exactly 14 pounds, so the stones-and-pounds form is the same number expressed differently rather than a separate conversion.
