Why do bathroom scales in the UK show stone and pounds together?
British and Irish people traditionally state body weight as a whole number of stone plus leftover pounds, such as 11 stone 4, rather than a single decimal figure. Since one stone equals 14 pounds, the pounds reading only ever goes from 0 to 13 before rolling over to the next stone. Medical settings in the UK now often use kilograms instead, so it helps to know both.
