About this tool

The pound (lbs) is the imperial and US customary unit of mass, still used for body weight and everyday measurements in the United States and, informally, in the United Kingdom and Ireland.

The kilogram (kg) is the SI base unit of mass, used by nearly every other country in the world, and throughout science and medicine. A 1959 international agreement fixed the pound at exactly 0.45359237 kilograms, so this conversion is not an approximation.

You'll typically reach for this converter when reading a US weight, recipe or product label and needing the metric equivalent — for example, converting a bench-press or luggage weight quoted in pounds into kilograms.
