What does horsepower (water) measure?

Horsepower (water) measures the theoretical mechanical power needed to move water against a head, based on flow rate, head height, and fluid density.

Why convert horsepower (water) to milliwatt?

Converting to milliwatt allows comparison and integration of hydraulic power with electronic power ratings in engineering applications.

Are conversion results exact in practical situations?

Results represent ideal theoretical values; real-world values may differ due to inefficiencies and measurement variations.
