- Foot-pound force
The

**foot-pound force**, or simply**foot-pound**(symbol:**ft·lb**or_{f}**ft·lb**) is a unit of work orenergy (a scalar) and also a unit oftorque (a vector).There is actually no such thing as "foot-pounds". The correct term is "pound-feet".Foot-pounds is still a very common term.

**Unit of energy**One pound-foot is the amount of energy expended when a force of one pound acts through a distance of one foot along the direction of the force.

1 pound-foot is equivalent to:

watt ≈ 44.25372896 ft·lb_{f}/min

* 1horsepower (mechanical) = 33000 ft·lb_{f}/min = 550 lb-ft_{f}/s**Unit of torque**As a unit of torque, one pound-foot is the torque created by one pound force acting at a perpendicular distance of one foot from a pivot point.
