Kilograms to stone, the unit the UK and Ireland still use for body weight despite being metric almost everywhere else. Scales, doctors and fitness apps often report kilograms while people think in stone, so this is the everyday translation.
Frequently asked questions
How do I get stone and pounds rather than a decimal?
The whole number is your stone; multiply the remainder by 14 for the pounds. 80 kg ÷ 6.35029 = 12.598 stone, so 12 stone, and 0.598 × 14 = 8.4 lb — 12 st 8 lb. Nobody says "12.6 stone" out loud.
How many kilograms is one stone?
6.35029 kg. A stone is 14 pounds exactly, and a pound is 0.45359237 kg, so the two definitions chain together without any rounding.
