How to convert kilograms to stone
One kilogram equals 0.157473 stone, so multiply the number of kilograms by 0.157473:
st = kg × 0.157473
kg = st ÷ 0.157473 (1 st = 6.3503 kg)
Example: 50 kg → 50 × 0.157473 = 7.8737 st.
Going the other way, divide by 0.157473, or multiply by 6.3503; the stone to kilograms converter does it for you.
