What is Foot-pound per second?

The foot-pound per second is the fundamental unit of power in the imperial system, representing one foot-pound of work performed per second. It equals approximately 1.356 watts. Historically, James Watt defined one horsepower as 550 foot-pounds per second, making this unit the foundation of the horsepower concept. While rarely used directly in modern practice, it appears in engineering unit conversions and historical technical literature.

What is Watt?

The watt is the SI unit of power, named after Scottish inventor James Watt. One watt equals one joule of energy per second. Household LED bulbs use about 7 to 12 watts, a microwave oven uses 500 to 1,000 watts, and a hair dryer uses about 1,200 watts. Electricity bills are based on watt-hours, the product of power consumption in watts and time of use.
