What does “horsepower” mean for an Engine?

741 views

I’m confused about the meaning of this word. Is it how much a horse can pull translated into how much the engine can pull? Also, what is the actual “metric”? Why do we still use this? It seems archaic.

Also, what type of horse was originally used to get the measurement?

Horsepower is the average output of a horse throughout a day. Horses can still outpace horsepower fairly routinely, just not in a sustained way. When an engine is said to have “100 horsepower”, it means it has as much output as 100 horses on average
