How to Convert Pounds to Stone
1 lb = 1/14 stone. Divide pounds by 14 to get stone. So 154 lbs ÷ 14 = 11 stone. For values that don't divide evenly, the remainder gives you stone-and-pounds: 156 lbs ÷ 14 = 11 stone with 2 lbs left over, written as 11 st 2 lb. This is the standard UK format.
The notation makes the conversion intuitive once you're used to it. Adults typically weigh 8-15 stone (112-210 lbs); body weight charts in the UK universally show stone-and-pounds because the granularity is comfortable for everyday use - one pound is a small, meaningful weight change, but a stone is a notable milestone.

Frequently Asked Questions
