Pounds to Stone Converter

Last updated: September 16, 2026

Stone is still the everyday unit for body weight in the UK and Ireland — NHS medical forms, bathroom scales, and newspapers all use it. Americans visiting the UK or reading British health content often see a weight in stone and need it in pounds to make sense of it. For the reverse, the stone to pounds converter handles st → lbs.

Formula: Pounds to Stone

The stone is defined as exactly 14 international avoirdupois pounds. One stone also equals 6.35029 kilograms. To convert the other way: multiply stone by 14 to get pounds, or multiply by 6.35029 to get kilograms.

Stone with remaining pounds

Body weight in the UK is usually given as stone and pounds — for example, "11 st 6 lbs." To get there from a whole pound figure:

1. Divide pounds by 14 — the whole number is the stone
2. The remainder is the extra pounds

Example: 162 lbs ÷ 14 = 11 remainder 8 → 11 stone 8 pounds

Writing Stone and Pounds Together

In British English, body weight is almost always expressed as stone and pounds — never as a decimal stone figure. Common conventions:

• Written: "11 stone 6 pounds" or "11 st 6 lb"
• Spoken: "eleven six" (the stone is implied)
• Scales display: "11:06" or "11.6" — the digit after the colon or decimal is pounds, not tenths

To convert to kilograms instead of stone, the lbs to kg converter gives the metric figure directly. For grams and ounces on lighter objects, see the ounces to grams converter.
