How to convert weight units
The kilogram is the base unit of mass in the International System of Units (SI). One pound is defined as exactly 0.45359237 kilograms — this is the fixed international standard since 1959. All other imperial weight conversions derive from this definition.
To convert kilograms to pounds, multiply by 2.20462. To convert pounds to kilograms, multiply by 0.453592. For example, 70 kg × 2.20462 = 154.32 pounds.
Stone is a unit used primarily in the UK and Ireland for body weight. One stone equals 14 pounds or 6.35 kilograms. So a person weighing 11 stone = 154 pounds = 69.85 kg.
