Pounds
The pound (avoirdupois) is a unit of mass equal to exactly 0.45359237 kilograms, standardised in 1959. It is the primary unit of mass in the US customary and British imperial systems, used for body weight, food packaging, and commercial transactions. The pound is subdivided into 16 ounces. In US engineering, the distinction between pound-mass (lbm) and pound-force (lbf) is a frequent source of calculation errors.

Standardised by the Weights and Measures Act of 1835, the stone persists in British popular culture and medical contexts despite not being part of the SI system.
