Say your gym scale shows 85 kg and you want to know what that is in stone.

1. Divide by 6.35029: 85 ÷ 6.35029 = 13.386...
2. The whole number is your stone: 13 stone.
3. Take the leftover decimal (0.386) and multiply by 14 (there are 14 pounds in a stone): 0.386 × 14 = 5.4 lb.
4. Result: 85 kg = 13 stone 5.4 lb.

The converter above does all of this in the background and shows you the tidy answer.

How the calculation works

A stone is a unit of weight used mainly in the UK and Ireland, equal to exactly 14 pounds or 6.35029 kilograms. To convert kilograms to stone, you divide by that number.

stone = kg ÷ 6.35029

To also get the remaining pounds (the bit left over after the whole stone):

total_pounds = kg × 2.20462
whole_stone  = floor(total_pounds ÷ 14)
remaining_lb = total_pounds mod 14

Quick tips and common mistakes

• Don't confuse stone with pounds. 1 stone = 14 pounds. Dividing kilograms by 2.205 gives you pounds, not stone — a very common slip.
• Stone is not used worldwide. Outside the UK and Ireland, almost no one uses stone. If you're filling in a form for a US or Australian service, they'll want pounds or kg directly.
• Rounding matters for body weight. Scales often show one decimal place in kg. A reading of 70.4 kg = 11 stone 1.0 lb, not 11 stone exactly — the converter handles this precisely.
• Decimal stone vs stone and pounds. "13.4 stone" and "13 stone 5.6 lb" express the same weight differently. The converter shows both so you can use whichever format you need.
