What does 1 horsepower [hp, hp (UK)] represent?

It is a mechanical power unit defined as 550 foot-pounds per second, approximately equal to 745.7 watts.

How is water horsepower calculated?

Water horsepower measures theoretical power to move water and is determined by factors like flow rate, head, and fluid specific gravity.

Can this tool convert metric horsepower to water horsepower?

No. The conversion specifically applies to mechanical/imperial horsepower (hp, hp UK) only.
