IPA: /ˈhɔːrspɑʊər/
KK: /ˈhɔrsˌpaʊər/
A measure of power used to describe the strength of engines or machines, equivalent to a specific amount of watts.
The car's engine produces 300 horsepower, making it very powerful.
Horsepower is formed from "horse" (from Old English "hors", meaning a domesticated animal used for riding or labor) and "power" (from Latin "potentia", meaning ability or strength). The term horsepower originally referred to the power exerted by a horse in performing work, particularly in relation to engines and machinery.
Think of a 'horse' as a strong animal used for work, and 'power' as the strength it provides. This helps you remember that 'horsepower' measures the strength or ability of engines, just like a horse would provide power.
