Convert Stone to Pound

What this conversion means in practice

Bathroom scales in the UK may show stone (sometimes with leftover pounds); US travel and shipping want a single pound total. Multiply stone by fourteen before comparing to lb-only charts.

Eleven stone is 154 pounds—handy when a training plan quotes lb but the athlete reads st. Adding leftover pounds matters: 11 st 4 lb is 158 lb, not 154 lb.

If your source shows “11.4 st,” confirm whether the decimal is a true decimal stone or a shorthand—mixed notation causes most errors here.
