About Power Converter

Power Converter switches between watts, kilowatts, megawatts, mechanical horsepower, and metric horsepower (PS). Engineers and car buyers searching "watts to horsepower", "kW to hp", or "power converter" need consistent power unit maths.

Enter a value, choose From and To units, and read the result. Mechanical hp and metric PS differ slightly - use the matching unit from the vehicle or motor datasheet.

Electrical power in kW and mechanical horsepower are related but not identical concepts in every context (efficiency losses matter in real machines). Converter maths assumes standard conversion factors.
