How the lbs to stone converter splits a weight
Type a weight in pounds and the result comes back in two parts: whole stones, then the pounds left over. The page opens on 180 lb, which reads 12 st 12 lb. The list below also gives the decimal stone, kilograms and ounces.
A stone is exactly 14 pounds under the UK Weights and Measures Act 1985, and the pound is 0.45359237 kg (NIST). Going from pounds to stone is a division by 14: the whole number gives the stones, the remainder the pounds. 180 divided by 14 is 12, with 12 left over. The lbs to stone converter does it for any figure, decimals included, so 150.5 lb shows 10 st 10.5 lb.
Mental shortcut: count in fourteens, with 7 lb as half a stone. 161 lb is 154 plus 7, so eleven and a half stone, or 11 st 7 lb. The leftover pounds keep one decimal, and a remainder that rounds up to 14 becomes a whole stone: 195.98 lb reads 14 st 0 lb, not 13 st 14 lb.
