What is a Horsepower (HP)?

ImperialUnited States, United Kingdom

Horsepower (HP) is a unit of power that measures the rate at which work is done, historically defined by the power needed to lift 550 pounds one foot in one second.

History

The term horsepower was first coined by James Watt in the late 18th century to market his steam engines. He calculated it based on the work performed by horses in coal mines, making it relatable to the average person of that time.

Current Use

Horsepower remains a standard unit in the automotive industry, used to describe the power output of engines, as well as in various mechanical systems where power measurement is essential.
