The pound-force (symbol: lbf, sometimes lbf) is a unit of force used in some systems of measurement including English Engineering units and the British Gravitational System. Pound force should not be confused with foot-pounds or pound-feet, which are units of torque, and may be written as "lbf⋅ft". They should not be confused with pound-mass (symbol: lb), often simply called pounds, which is a unit of mass.

A kip is a US customary unit of force. It equals 1000 pounds-force, used primarily by American architects and engineers to measure engineering loads. Although uncommon, it is occasionally also considered a unit of weight, equal to 1000 pounds, i.e., one half of a short ton. One use is as a unit of deadweight to compute shipping charges.
