In physics, a foot-pound (symbol ft·lbf or ft·lbf) is an Imperial and U.S. customary unit of mechanical work, or energy, although in scientific fields one commonly uses the equivalent metric unit of the joule (J). There are approximately 1.356 J/(ft·lbf).
To calculate a foot-pound, you can use this formula,
- W = F × D
where W is work (in foot-pounds), F is force (in pounds), and D is distance (in feet) over which the force is applied (measured in the direction of the force).
Doing 550 foot-pounds of work on an object in one second is equal to a horsepower, an Imperial and U.S. customary unit of power.
