How this is calculated
stone = kg ÷ 6.35029318 (exact)
The gym-scale-to-conversation direction: 70 kg is 11.02 st (11 st 0.3 lb), 85 kg is 13.39 st (13 st 5.4 lb), 100 kg is 15.75 st (15 st 10.4 lb). The decimal stone is the machine’s answer; splitting the remainder into pounds (×14) is how people actually say it.
Same exact 6.35029318 kg definition, inverted. Note the rounding trap: 0.5 st is 7 lb, so “about 13 and a half stone” spans nearly 3 kg — the pounds split exists because decimals of a stone are too coarse for tracking.
