Stone to Pounds Converter

Convert British stone and pounds

Stone remains a familiar way to express personal weight in the United Kingdom and Ireland, while pounds are more widely understood in the United States. The relationship is exact: one stone contains 14 avoirdupois pounds. This converter supports decimal values in either direction and shows common reference points.

The default 12 stone converts to exactly 168 pounds. In reverse, 140 pounds converts to exactly 10 stone. A value such as 11.5 stone can also be entered and returns 161 pounds. The result uses decimal stone rather than separating an answer into stone plus leftover pounds.
