Horsepower to Kilowatts Converter

Summary

Enter horsepower (mechanical, electrical, or metric PS) to get kilowatts instantly, with a reference table of common engines and motors.

How it works

1. Enter a horsepower value in the input field.
2. Select the HP type: mechanical, electrical, or metric (PS/CV).
3. The tool multiplies the hp value by the conversion factor for that type.
4. Mechanical hp uses 1 hp = 0.74569987 kW; electrical hp uses 1 hp = 0.746 kW; metric PS uses 1 PS = 0.73549875 kW.
5. The kilowatt result updates instantly as you type.
6. Switch to the kW to HP tab to reverse the conversion.
7. Click any row in the reference table to load that value into the converter.

Use cases

• Convert a car engine rating from horsepower to kilowatts for European market comparison.
• Translate motor nameplate data between hp and kW for equipment selection.
• Check whether a motor rated in hp meets a minimum kW requirement in a spec sheet.
• Compare US horsepower and European PS figures for the same vehicle.
• Convert generator hp output to kilowatts for load planning.
• Cross-check pump or HVAC ratings listed in hp against kW-based selection charts.
• Verify engine power conversions when importing or exporting machinery.
