Unit Definitions
What is a Horsepower (HP)?
Horsepower (HP) is a unit of power used to measure the rate of doing work.
History
The term was coined by James Watt in the late 18th century to compare the output of steam engines with draft horses. It has since been standardized to 550 foot-pounds per second.
Current Use
Today, horsepower is commonly used to describe the power of engines and motors in vehicles and machinery.
