How the conversion works

The relationship between these units is exact: one stone equals 14 pounds. To convert stone to lbs, multiply by 14. For example, 11 stone is 11 x 14 = 154 pounds.

To go from pounds to stone, divide by 14. The whole number part is the stone count, and the remainder is the leftover pounds. For 160 pounds: 160 / 14 = 11 with a remainder of 160 - (11 x 14) = 6, giving 11 st 6 lb.

Where stone and pounds are used

The stone is a unit of mass in the British imperial system, still widely used in the United Kingdom and Ireland for measuring body weight. A person might say they weigh 11 stone rather than 154 pounds. In the United States, pounds are the standard unit for body weight, so converting stone to lbs is helpful when reading British media or communicating across regions.

Sports like boxing and horse racing also use these units. Boxing weight classes in the UK are often announced in stone, while international records may list them in pounds. If you need to convert to metric units afterward, tools like kg to lbs or grams to pounds can help bridge the gap.

Expressing pounds as stone and pounds

When converting lbs to stone, the result is often expressed as a combination of whole stones and remaining pounds rather than a decimal. Saying "11 stone 6" is more natural in everyday British English than "11.43 stone." This converter provides both formats so you can choose whichever fits your context.

The calculation takes the integer part of the division by 14 as the stone value and the modulus (remainder) as the pounds. For fractional pound inputs, the remainder preserves the decimal portion. For example, 161.5 pounds becomes 11 stone and 7.5 pounds.

Relationship to other weight units

One stone is exactly 14 pounds, which equals approximately 6.35 kilograms (using the international pound definition of 0.45359237 kg). There are 2240 pounds in an imperial long ton, which is exactly 160 stone. For smaller measurements, one pound contains 16 ounces, so one stone contains 224 ounces. If you need to break down pounds further, the pounds to ounces converter handles that step, and ounces to pounds and ounces reverses it.
