Half stones are how most of us in Britain actually talk about weight, and 16.5 is a figure I see quoted on boxing and rugby weigh-ins, where that half stone really matters. It sits a fraction under 105 kg (104.78, to be exact), which is why you will sometimes see the two numbers used almost interchangeably. If you are stepping on a dial scale marked in stones, the needle lands exactly halfway between 16 and 17 stone, at 16 stone 7 pounds.

Same weight, very different picture, so find your own height row in the table. BMI is a screening measure, not a diagnosis.
