This calculator is for comparing spec sheets, equipment labels, and regional engine ratings when one source uses kilowatts and another uses horsepower.

Tips

Use this tool for unit conversion only; it does not infer power from torque or RPM on its own.
Quoted ratings may still differ by test standard even after the units are converted correctly.
