Half-stone figures confuse more people than any other weights I deal with. Nobody in Britain says "seven point five stone"; they say "seven seven", meaning 7 stone 7 lb. Digital scales that show decimals make it worse, flashing 7.5 when the old dial showed 7 st 7 lb. They are the same weight, and 47.63 kg is the metric answer for both. Our stone to kg chart lists every half-stone step if you want to compare.
