The derived unit of mass in the English system is called a slug: 1slug = (l lbf) / (1ft/s2) There is also a unit of mass in the English system called the pound (lbm): 1lbm=(32.2 lbf) / (1ft/s2) Hence 1 lbm= 32.2 slugs. The metric system defines mass to be a basic physical quantity. Hence the unit for mass is a base unit and the unit for force ...

1 lbf = 32.174 lbm•ft•s-2. Because this unit conversion factor is based on a standard gravitational acceleration, it is a fixed number, which is always the same regardless of the local gravitational acceleration. The weight of a mass is the product of the mass times the local gravitational acceleration.
