Calculate a Vehicle's Power in Horsepower or Kilowatts

The kilowatt and horsepower are units for measuring the power of cars or any other motor vehicle.

What is horsepower?

Horsepower is a unit of power that relates the strength of a horse to that of an engine. This converter uses mechanical horsepower (1 hp = 745.7 W), the standard in the United States.

Metric horsepower (PS)

In Europe, car power is often given in metric horsepower (PS or CV), which is slightly different: 1 PS ≈ 0.9863 hp. Keep this in mind when comparing European and American spec sheets.

What is a kilowatt?

The kilowatt is a unit that expresses the power of a device. It is the unit of measurement that vehicle manufacturers must provide to inform users about the power of their machines.

Convert kW to horsepower

Horsepower is still widely used. Some users want to know the horsepower equivalent of a kilowatt figure and vice versa. This calculator lets you convert them.

Conversion result

When necessary, the converter rounds the result (maximum 3 digits after the decimal point).

Why convert?

Converting a vehicle's power is useful for users who want to know the actual power of their vehicle. It also makes it possible to compare the power of different vehicles.
