What does a millijoule per second measure?

A millijoule per second (mJ/s) measures power as the rate of energy transfer, equal to 0.001 joules per second, often used to describe low-power electronic systems.

What is water horsepower used for?

Water horsepower is used to calculate mechanical power required to move water in systems such as pumps for irrigation, HVAC, and municipal water supply.

Can I directly compare millijoule/second to water horsepower?

Direct comparison is limited since millijoule/second applies to very low power levels, while water horsepower relates to larger hydraulic power scales and assumes ideal fluid conditions.
