horsepower

Horsepower is a unit of measurement for engine power, representing how much work an engine can do over time. It originated in the 18th century to compare the power of steam engines to draft horses. Specifically, one horsepower equals the ability to perform 550 foot-pounds of work per second, which is roughly the power needed to lift 550 pounds one foot in one second. In practical terms, higher horsepower indicates a more powerful engine capable of generating greater speed and performance in vehicles, machinery, or tools. It’s a useful way to compare the strength and capability of different engines or motors.
