About this tool

Mass is how much matter something contains – in everyday language its weight. The metric world uses grams, kilograms and tonnes; the US and UK use ounces, pounds and, for body weight in Britain, stone.

Here every value is converted through the kilogram (kg). Choose any two of the 14 units below the converter, or start from one of the popular conversions.
