Questions
How many pounds is one kilogram?
1 kg = 2.20462 lb, and the figure is exact by definition: since 1959 the international pound has been defined as exactly 0.45359237 kg, so the conversion never drifts and never needs updating.
What is the formula for kg to lbs?
Multiply kilograms by 2.2046226218, equivalently divide by 0.45359237. Going the other way, multiply pounds by 0.45359237 to get kilograms.
Which is heavier, a kilogram or a pound?
A kilogram. One pound works out to 0.4536 kg, so a kilogram is a little over twice as heavy: 100 kg is 220.46 lb, not 100-something.
How exact should my number be?
Two decimals are already past the precision of any bathroom scale: 80 kg is 176.37 lb, and the digits after that matter in lab, freight or engineering contexts only. For luggage and body weight, whole pounds are fine.
Does the converter work without a connection?
Yes, once the page has loaded. The conversion is a multiplication your browser performs locally, nothing is uploaded, and reloading the page offline still works from cache.
