The Stone Unit
The stone (symbol: st) is a unit of mass in the British imperial system equal to exactly 14 pounds (lb), or about 6.35029 kilograms. To convert stone to pounds, multiply by 14; to convert pounds to stone, divide by 14.
For example, 10 stone equals 140 pounds (10 × 14), and 140 pounds equals 10 stone (140 ÷ 14). Body weight is often expressed in "stone and pounds", such as 11 st 4 lb.
Where the Stone Is Used
The stone remains in everyday use in the United Kingdom and Ireland for measuring human body weight, even though it has been officially replaced by the kilogram for most other purposes. In these countries, a person's weight is commonly stated in stone and pounds rather than in pounds alone or in kilograms. The unit is rarely used in the United States, where pounds are preferred, or in countries that use the metric system exclusively.
