What Is This Tool?
This converter transforms power values measured in horsepower (water), a unit used for hydraulic power calculations, into hectojoule per second (hJ/s), a unit representing the rate of energy transfer equal to 100 watts. It helps translate hydraulic power into standardized electrical and thermal power units.
How to Use This Tool?

Hectojoule/second is less commonly used than watts and may cause confusion in some contexts
Frequently Asked Questions
-
What is horsepower (water) used for?
-
Horsepower (water) is used to quantify the mechanical power transferred to move water against a given head, commonly applied in pump sizing and hydropower estimations.
-
How is hectojoule per second related to watts?
-
One hectojoule per second equals 100 watts, measuring how quickly energy is delivered or transformed.
-
Why convert horsepower (water) to hectojoule/second?
-
Converting to hectojoule/second standardizes hydraulic power into electrical or thermal power units, helping compare performance across different systems.
