Mass units around the world

Most countries use grams and kilograms. The US uses ounces and pounds, the UK commonly uses stone for body weight, and precious metals use troy ounces (31.1 g) – different from the ordinary ounce (28.35 g). Some regions also have traditional units for gold and grain, which this converter includes.

Practical examples

A 500 g pack is 17.6 oz; a 2 kg bag of flour is 4.4 lb; 80 kg body weight is 12 st 8 lb. When shipping parcels, carriers often round up to the next whole kilogram or pound, so convert before you buy postage.

Cooking with weights

Weighing ingredients is more accurate than using cups. Many US recipes give ounces and pounds; converting to grams lets you use a kitchen scale set to metric for consistent results.
