Why This Number Matters
British and Irish sources give body weight in stones, so an American reading a UK health article, recipe show or forum post needs this number to make sense of it.
10 stone is exactly 140 pounds, which is why 10 stone is a common target weight in the UK.
What People Get Wrong
"11 stone 4" means 11 stone plus 4 pounds, which is 158 pounds. Reading it as 11.4 stone gives 159.6 pounds instead.
