How to calculate
Type the weight in pounds and read the stone figure below. To convert by hand, divide pounds by 14: 154 pounds is 154 ÷ 14 = 11 stone. To express a remainder as pounds, take the leftover after the whole stones — 160 pounds is 11 stone and 6 pounds, because 11 × 14 = 154 with 6 left over. The result updates as you type.
stone = pounds ÷ 14, where 14 is the exact number of pounds in one stone. Equivalently, pounds = stone × 14. To split a result into stone-and-pounds, multiply the whole stones by 14 and subtract from the total to get the leftover pounds.
Example calculation
154 pounds divided by 14 pounds per stone is exactly 11 stone. The stone is a British unit of body weight equal to 14 pounds, so any pound figure converts by dividing by 14.

Assumptions
- One stone is defined as exactly 14 avoirdupois pounds, so the conversion is exact.
- The stone is used mainly in the UK and Ireland for body weight; it is rarely used in the US, where pounds alone are standard.
- The decimal result shows stone as a single number; people often quote body weight as whole stone plus leftover pounds instead.
Common mistakes
- Reading the decimal part as pounds — 11.5 stone is eleven and a half stone (7 pounds), not 11 stone 5 pounds.
- Forgetting that a stone is 14 pounds, not 10, when doing the split by hand.
- Mixing up the direction — divide by 14 for stone, multiply by 14 for pounds.
