How to use the weight converter
Type a weight and choose the units to convert from and to. The table below lists the same weight in every other unit. This is useful for recipes, luggage limits, parcels and body weight.
The formula
Every unit is defined in kilograms: result = value × (kg in the from-unit ÷ kg in the to-unit). A pound is exactly 0.45359237 kg, an ounce is one sixteenth of a pound and a stone is 14 pounds.
Worked example
To convert 70 kg to pounds: one kilogram is about 2.2046 lb, so 70 × 2.2046 = 154.32 lb.
