Weight and mass conversions matter most in three places: shipping, where a rate band can turn on a single kilogram; cooking, where recipes cross between metric grams and imperial ounces; and personal weight, where Britain and Ireland use stones, the United States uses pounds, and everywhere else uses kilograms. Strictly these are mass units rather than weight units, and the distinction only bites in physics, where weight is a force measured in newtons.

To go the other way, use stone = pound ÷ 14.
