The formula
How to convert stone to pounds
To change stone into pounds, multiply by 14.
pounds = stone × 14
Going the other way: stone = pounds ÷ 14
1 stone = 14 pounds. This factor is the exact definition of the unit, not a rounded estimate.
Worked example
You have 11 stone. Multiply by 14. 11 × 14 = 154 lb.

Before you rely on it
Convert the stone, then add the pounds
A UK weight is usually written as stone and pounds — 11 st 4 lb — and the two parts are treated differently. Multiply the stone by 14, then add the loose pounds on top: 11 st 4 lb is 154 + 4 = 158 lb.
Typing 11.4 into the converter is not the same thing. The pounds in "11 st 4 lb" are fourteenths of a stone, not tenths, so 11.4 st is 159.6 lb. Enter the whole stone only, and add the pounds yourself.
1 stone is exactly 14 pounds. That is a definition, so every whole-stone answer here is a whole number of pounds and nothing is rounded.
Stone is its own plural for body weight: "12 stone", not "12 stones", abbreviated st. If you need the weight in kilograms instead — for a medical form or a BMI calculator — stone to kilograms gives it directly.
