Foot-pound-force per second

The foot-pound-force per second (ft·lbf/s) is a unit of power in the imperial and US customary systems, representing the rate at which one foot-pound-force of work is done per second. One ft·lbf/s is approximately equal to 1.3558179 watts. Mechanical horsepower is defined as exactly 550 ft·lbf/s, making this unit fundamental to the definition of horsepower. It is used in engineering contexts involving mechanical work in imperial units.
