Tips & common mistakes

Quick tips

1 stone = 14 lb = 6.35 kg exactly.
British speakers often say "11 stone 4" meaning 11 stone and 4 pounds — not 11.4 stone.
Multiply stones by 6.35 for a precise kg conversion.

Avoid these

Reading "11 stone 4" as 11.4 stone — it is 11 × 14 + 4 = 158 lb.
Using stones outside UK/Ireland contexts — audiences elsewhere will not understand.
Multiplying by 6 instead of 6.35 for a quick kg estimate — 5% error.
