Mass versus weight
Everyday calculators often say weight, but these conversions are mass-unit conversions. They are appropriate for body weight, shipping estimates and general measurement.
Example
75 kg is about 165.35 lb. Since 1 stone is 14 lb, that is about 11.81 stone.
Common mistakes
Do not mix pounds and stone without converting. Also check whether a form expects kilograms, total pounds or stone plus remaining pounds.
Limitations
This is a unit converter only. It does not interpret healthy weight, shipping rules, medication dosing or any clinical context.
