Looking to convert pounds (lb) to stones (st)? Especially common in the UK and Ireland, the stone is a traditional unit of weight widely used for expressing body weight. This guide presents formulas, tables, examples, quizzes, and real-world tips for reliable conversions.
In the British Imperial and U.S. customary system, the conversion is:
1 stone (st) = 14 pounds (lb)To convert from pounds to stones, divide the pound value by 14. For example: 70 lb ÷ 14 = 5 st.
Stones = Pounds ÷ 14| Pounds (lb) | Stones (st) |
|---|---|
| 70 | 5 |
| 84 | 6 |
| 98 | 7 |
| 112 | 8 |
| 126 | 9 |
| 140 | 10 |
| 154 | 11 |
| 168 | 12 |
| 182 | 13 |
| 196 | 14 |
// Convert pounds to stones (decimal)
function poundsToStones(pounds) {
return +(pounds / 14).toFixed(2);
}
// Convert pounds to stones + pounds remainder
function formatStone(pounds) {
const st = Math.floor(pounds / 14);
const lbRemainder = pounds % 14;
return `${st} st ${lbRemainder} lb`;
}
console.log(poundsToStones(150)); // 10.71
console.log(formatStone(150)); // "10 st 10 lb"
168 ÷ 14 = 12 st.
145 ÷ 14 = 10 st with a remainder of 5 lb → 10 st 5 lb.
The stone is embedded in UK culture and tradition for expressing body weight — a quicker, less granular unit than pounds.
Use Pounds = Stones × 14. For example, 7 st × 14 = 98 lb.
Use this rhyme:
"One stone is fourteen pound,—
Keep it simple, wisdom found."
In the UK and Ireland, it's common to express weight in a two-part format, such as “12 stone 4 pounds”. Here's how it works:
For example, 154 pounds ÷ 14 = 11 stones with no remainder → 11 st. But 160 pounds ÷ 14 = 11 st and 6 lb → 11 st 6 lb.
Here’s how some typical weights translate into stone units:
| Weight | Pounds | Stones + Pounds |
|---|---|---|
| Lightweight Boxer | 135 lb | 9 st 9 lb |
| Average Female (UK) | 154 lb | 11 st |
| Average Male (UK) | 189 lb | 13 st 7 lb |
| Rugby Player | 220 lb | 15 st 10 lb |
