Pounds to Stone Conversion: A UK Weight Guide

Learn how to convert weight from pounds (lbs) to stone (st), a unit commonly used in the UK.

The Pounds to Stone converter is an essential tool for anyone familiar with or traveling to the United Kingdom, Ireland, and some Commonwealth countries where body weight is commonly measured in stone and pounds. This converter simplifies the process of switching from the purely pounds-based system used in the US to the stone and pounds system.

The Conversion Rule

The relationship between pounds and stone is a fixed part of the British Imperial System of measurement.

1 Stone = 14 Pounds

To convert a weight from pounds to stone, you divide the total number of pounds by 14. The whole number part of the result is the number of stone, and the remainder is the number of pounds.

Stone = Integer part of (Total Pounds / 14)

Remaining Pounds = Total Pounds % 14 (modulo)

Practical Examples

  • Body Weight: A person in the US weighs 150 pounds. To express this in stone and pounds:
    150 / 14 = 10 with a remainder of 10.
    So, 150 lbs is equal to 10 stone and 10 pounds.
  • Weight Loss Goal: Someone wants to lose 20 pounds. In stone, this is:
    20 / 14 = 1 with a remainder of 6.
    So, a 20 lb weight loss is equivalent to losing 1 stone and 6 pounds.
  • Boxing Weight Class: A boxer weighs exactly 147 pounds (the welterweight limit). This is:
    147 / 14 = 10 with a remainder of 7.
    This is equal to 10 stone and 7 pounds.
