The pound is an Anglo-American unit of weight and does not belong to the SI International System of Units (Système international d'unités). Many different definitions have been used, but today the international avoirdupois pound is the most common unit and is officially defined as exactly 0.45359237 kilograms.

Thus, 1 pound is equivalent to 0.45359237 kilograms, and 1 kilogram is equivalent to 2.20462262 pounds.

The avoirdupois pound described here is equivalent to 16 ounces and should not be confused with the troy pound, which is now used only rarely for precious metals and is derived from the troy ounce.

The kilogram is the basic unit of mass, i.e., weight. Since 1889 it has been defined by the mass of the international prototype kilogram or original kilogram. This is a cylinder made of platinum-iridium, which is kept in a safe by the International Office of Weights and Measures in Paris.

All other units of mass or weight in the metric system are derived from the kilogram (e.g., 1 t = 1 000 kg, 1 kg = 1 000 g).
