About converting stones to pounds
Stones to pounds unpacks the British body-weight unit into the pounds used on US scales and medical charts.
One stone is exactly 14 pounds, a fixed whole-number relationship, so converting stones to pounds is simply multiplying by 14. A weight of 10 stone is 140 lb, 12 stone is 168 lb, and 14 stone is 196 lb.
The stone remains in everyday use in the UK and Ireland for personal body weight, even though it has largely disappeared elsewhere. British weights are often given as 'stone and pounds' — for example '11 stone 4' means 11 × 14 + 4 = 158 lb — so the conversion frequently involves adding the leftover pounds after multiplying.
- Multiply the stone figure by 14, then add any extra pounds quoted alongside it.
- To reach kilograms, convert to pounds first, then multiply by 0.4536.
