How to use the stone to lbs converter
The weight goes into two fields: stones first, then any extra pounds. The page opens on 12 st 0 lb, which comes to 168 lb. Leave the second field at 0 for a round number of stones, or type 12 st 7 lb to get 175 lb. The list below adds kilograms, the decimal stone and ounces.
Going from stones to pounds is a multiplication: stones times 14, plus the pounds on top. A stone is defined as 14 pounds in the UK Weights and Measures Act 1985, with the pound set at 0.45359237 kg (NIST). The stone to lbs converter applies it exactly, so 9 st 11 lb gives 137 lb, and half a pound in the second field stays in the result.
Mental shortcut for stones to pounds: times 14 is times 10 plus times 4, so 13 st is 130 plus 52, or 182 lb. If all you have is a decimal stone, such as 9.5 st, pick Stone as the starting unit instead: 9.5 st is 133 lb.

British weights from stones to pounds
A visit to a doctor or a gym in the US, or a new American fitness app, means giving your weight in pounds. Someone who weighs 11 st 3 lb enters 157 lb, since 11 times 14 is 154. The stone to lbs converter gives that figure without the mental arithmetic, and the kilograms sit in the list for a form that accepts either.
It helps American readers too. UK newspapers and TV describe people in stones: a man of 18 stone weighs 252 lb, and 8 st 4 lb is 116 lb. Type such a figure into the stone to lbs converter and read the pounds.
Horse racing in Britain and Ireland prints the weight each horse carries in stones and pounds, but talks about the gaps in pounds: 11 st 10 lb is 164 lb, so a rival on 10 st 12 lb carries 12 lb less. The allowance an apprentice jockey claims is given in pounds as well, such as 3 lb or 7 lb. To turn a weight in pounds back into stones, use the lbs to stone converter, while the stone to kg converter gives kilograms.
