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.

About these units

The international avoirdupois pound is exactly 0.45359237 kilograms — defined in terms of the metric system, not the other way round.

The gram is a thousandth of a kilogram. It is the base unit of nearly every recipe outside the US, and the reason kitchen scales beat cup measures for consistency.

Pound is also written pounds, lbs and #. Gram is also written gramme, grammes, grams, gm and gms.
