A joule (J) is an SI derived unit of energy equal to the work done when a force of one newton moves an object one meter; it also equals one watt-second.

What does one metric horsepower hour represent?

One metric horsepower hour is the energy delivered by sustaining one metric horsepower (735.49875 watts) for one hour.

Can I use this converter for imperial horsepower conversions?

No, this tool is specific to metric horsepower and applying it to imperial horsepower requires different conversion factors.
