About horsepower and foot-pounds per second
The Conversion Formula
To convert horsepower to foot-pounds per second, multiply the value by the conversion factor: 1 hp = 550 ft·lbf/s. For a worked example, suppose you need to convert 25 hp to foot-pounds per second: 25 × 550 = 13749.98 ft·lbf/s. To convert in the opposite direction, divide by 550, or equivalently multiply by 0.00181818.
About horsepower
Horsepower (hp) was coined by James Watt to market his steam engines to millers who used horses. He calculated that a horse could do 33,000 foot-pounds of work per minute. It remains the dominant unit for cars, boats, and lawnmowers in the US, despite being an archaic estimation of an animal's strength. horsepower are commonly used in Car engines, Lawnmowers, Boat motors, and Industrial pumps (US), Marketing materials.
A Toyota Camry has about 200 horsepower.
About foot-pounds per second
The foot-pound per second is the base unit of power in the English engineering system. It is defined as the power needed to lift 1 pound 1 foot in 1 second. 550 of these equal 1 horsepower. It is mostly used in engineering textbooks today. foot-pounds per second are commonly used in Mechanical engineering, Physics problems (US), Torque/Power derivations, and other fields.
Lifting a 1lb book 1ft in 1s takes 1 ft-lb/s of power.
When Would You Convert horsepower to foot-pounds per second?
