The foot-pound force (symbol: ft·lbf) is a unit of work or energy in the Engineering and Gravitational Systems in United States customary and imperial units of measure.

It is the energy transferred upon applying a force of one pound-force (lbf) through a linear displacement of one foot.

Foot-pound is sometimes also used as a unit of torque. In the United States this unit is often used to specify, for example, the tightness of a bolt or the output of an engine. Although they are dimensionally equivalent, energy (a scalar) and torque (a vector) are distinct physical quantities.
