What is the Horsepower to Kilowatts Converter?

The Horsepower (HP) to Kilowatts (kW) converter bridges mechanical engineering with electrical engineering. It is used worldwide to translate the physical turning power of an engine or electric motor into standardized metric energy consumption.

How It Works (Formula)

The tool supports both Mechanical Horsepower (used in the US/UK) and Metric Horsepower (used in Europe/Asia). One Mechanical HP is exactly 745.699872 Watts (or 0.745699 kW), while one Metric HP is slightly weaker at 0.735498 kW. The calculator applies these precise multipliers.

$$ P_{(\text{kW})} = P_{(\text{Mechanic HP})} \times 0.745699872 $$

The multiplier to convert Imperial rotary force into Metric kilowatts.

How to Use It

Enter the power of the engine or motor in Horsepower (HP). Specify whether it is Mechanical HP, Electrical HP, or Metric HP. The calculator will apply the correct coefficient and output the exact rating in Kilowatts (kW).
