Wikipedia

The foot-pound force, or simply foot-pound (symbol: ft·lb_f or ft·lb) is a unit of work or energy (a scalar) and also a unit of torque (a vector).

Unit of energy

One foot-pound 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 foot-pound is equivalent to:

1.3558179483314004 joules (exactly)
13558179.483314004 ergs (exactly)
12 inch-pound force (exactly)
192 inch-ounce force (exactly)
0.001285067 British Thermal Unit
0.323832 calorie
0.000323832 "food calorie"
32.174049 foot-poundals

Related units of power

The foot-pound force per minute (ft·lb_f/min), foot-pound force per second (ft·lb_f/s), and horsepower are units of power derived from the foot-pound force.

1 watt ≈ 44.25372896 ft·lb_f/min
1 horsepower (mechanical) = 33000 ft·lb_f/min = 550 ft·lb_f/s

Unit of torque

As a unit of torque, one foot-pound is the torque created by one pound force acting at a perpendicular distance of one foot from a pivot point. The term pound-foot is sometimes used to distinguish the unit of torque from the unit of energy. Pound-foot is used by engine manufacturers in specifying the torque output of an engine.
