Stone to Kg Converter
Convert body weight between stone, pounds and kilograms.
The stone, and everyone else
Body weight is quoted in stone and pounds in the UK and Ireland, in pounds alone in the US, and in kilograms almost everywhere else — so a weight from one place regularly needs translating for another. This converts between stone, pounds and kilograms, handling the fact that a stone is fourteen pounds so you do not have to.
Enter a weight in any of the three and see it in the others.
Why the stone persists
The stone is an oddity — fourteen pounds, used almost nowhere but Britain and Ireland and almost only for body weight — which is exactly why it causes confusion for everyone else. Converting a weight given in stone and pounds means combining two numbers with a fourteen-to-one relationship, then translating to kilograms, which is fiddly by hand. For medical records, international forms, or simply comparing figures across systems, having all three units at once removes the mental arithmetic and the risk of getting the fourteen wrong.
