Horsepower Converter
Convert between kilowatts, mechanical horsepower, and metric horsepower (PS).
Engine power is expressed in different units depending on the region. The United States and United Kingdom use mechanical horsepower (HP), continental Europe and Japan use metric horsepower (PS or CV), and the SI standard is kilowatts (kW).
One mechanical HP equals 745.7 watts, while one metric PS equals 735.5 watts — a difference of about 1.4%. Electric vehicles are typically rated in kW, while internal combustion engines are marketed in HP or PS depending on the market.
This converter lets you enter a value in kW and see the equivalent in all three systems. Knowing these conversions helps when comparing vehicles from different countries or reading international specification sheets.
