About This Conversion
Stones to kilograms turns a spoken British weight into the figure a metric medical record, airline or gym needs. Multiply by 6.35029318, or by 14 and then 0.45359 if you prefer to go through pounds.
Clinical use is where precision matters, because drug dosing is per kilogram. A patient reported as "about 13 stone" spans 82.5 to 83.9 kg depending on how the pounds were rounded away, which is enough to shift a weight-based dose.
A few anchors help as a sanity check: 10 st is 63.5 kg, 12 st is 76.2 kg and 15 st is 95.3 kg. A stone is a little over six and a third kilograms, so multiplying by 6.35 in your head is accurate to within a gram per stone.
