How to convert stone to kg
Multiply stone by 6.35. If you have pounds as well, turn them into part of a stone first.
Pounds ÷ 14 turns the pounds into a fraction of a stone. 4 lb ÷ 14 = 0.29.
Add that number to the whole stone. 11 + 0.29 = 11.29 stone.
Stone × 6.35 gives kilograms. 11.29 × 6.35 = 71.7 kg.
Example: 11 st 4 lb
(11 + 4 ÷ 14) × 6.35029 = 71.7 kg
