How to convert kg to stone
One stone is 6.35029 kg, so to convert kilograms to stone you divide by 6.35029.
Formula: stone = kilograms ÷ 6.35029
Example: 80 kg ÷ 6.35029 = 12.6 stone. To express that in stones and pounds, multiply the decimal part by 14: 0.6 × 14 ≈ 8.4, so 80 kg is about 12 st 8 lb.
Tip: Bathroom scales in the UK often show “st lb”, for example 12 st 8 lb. That is stones plus pounds, not a decimal.
