Foot-pound
In physics, a foot-pound is the 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 approxmately 1.356 J per foot-pound.
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, the Imperial and U.S. customary unit of power.
