Why the units trip everyone up

British scales read in stones and pounds, gym equipment is labelled in kilograms, and most tracking apps default to one or the other. The awkward part is the base-14 maths: decimals on a scale are fractions of a stone, not of ten. Use the converter at the top of this page, or the charts above, whenever you need stones, pounds and kilograms side by side. Once you have a weight you trust, pair it with the maintenance calorie calculator if you are setting nutrition targets.
