How to convert kilograms to pounds

A kilogram is the SI unit of mass. A pound (lb) in everyday US use is the international avoirdupois pound. The exact factor is:

1 kilogram = 2.2046226218 pounds

Worked example

To convert 70 kg to pounds, multiply 70 × 2.2046226218. The result is about 154.32 lb. To go the other way, multiply pounds by 0.45359237.

When precision matters

Shipping labels, gym logs and cooking often need only one or two decimal places. Laboratory or aviation work may need the full factor. DEVTOOLIO’s KG → LBS and LBS → KG pages use the international pound, not a rounded 2.2 shortcut.

Weight is not the same as force

In casual speech people say “weight in kilos”. Strictly, a kilogram is mass. Bathroom scales estimate mass from force due to gravity. For everyday health tracking the distinction rarely changes the number you write down.
