Before you rely on it
The answer is decimal stone, not stone and pounds
Stone is almost only used for body weight, and almost only in Britain and Ireland. It is never spoken as a decimal: nobody says "11.02 stone", they say "11 stone and a bit" or "11 st 4 lb".
To read the decimal as stone and pounds, multiply whatever follows the point by 14. 70 kg is about 11.02 st, and 0.02 × 14 is roughly 0.3 lb, so 70 kg is essentially 11 st 0 lb.
1 stone is exactly 14 pounds, and therefore exactly 6.35029318 kg. The 14 is a definition; the kilogram figure follows from the pound being exactly 0.45359237 kg.
This unit is not used in the United States, where body weight is given in pounds alone, nor in metric countries, where it is kilograms. If you are filling in a medical form, use the unit the form asks for.
