How it works
The calculator divides kilograms by 0.45359237 to obtain pounds. Then it divides pounds by 14. 70 kg is 11 st and 0.32 lb.

Stone is a British mass unit. The pounds-to-kg page has no stone field.
You may enter zero; the result is then also zero. The calculator does not accept negative numbers.
The page does not judge body weight. 70 kg is 11 st and 0.32 lb whether that is a person or a sack.
A comma and a period give the same fraction.
Formula
lb = kg / 0.45359237; st = floor(lb / 14); remainder = lb − 14 × st
1 stone = 14 lb. 1 lb = 0.45359237 kg since 1959.
