Car Power Converter: Convert BHP, PS & KW

Brake horsepower (BHP), horsepower (also referred to as ‘PS’ or ‘Pferdestärke’) and kilowatts (kW) are three different metrics that are often used to measure engine power. They are all regularly cited in car advertisements, reviews and other automotive media.

Our car power calculator tool allows you to easily convert between bhp, kW, and PS, so you can accurately determine your vehicle's power output.

Engine Power Measurements Explained

Different manufacturers and publishers use different engine power metrics, this can sometimes lead to confusion among readers.

For instance, you may be familiar with BHP (and have a good idea of what can be considered a ‘powerful’ engine reading in that metric). However, when ads and articles cite engine power in PS or kW, interpreting these statistics can be tricky if you are unfamiliar with the metrics used.

Similarly, if you are comparing the engine power of one car model to another, but different metrics are used on the respective manufacturers’ websites, it can be difficult to gauge which model has the more powerful engine.

Are you unfamiliar with the various engine power measurements and what they mean? Here is a quick explainer:

Horsepower (BHP)

Brake horsepower (BHP) refers to a car’s horsepower after accounting for the friction between its tyres and the road. Therefore, a BHP figure will always be lower than the equivalent horsepower (PS) reading.

Horsepower (PS)

Horsepower is often shortened to ‘PS’ (this stands for Pferdestärke - and translates to ‘horsepower’ in German’).

This PS metric refers to how much power a car’s engine can produce. It is calculated through the power needed to move 550 pounds 1 foot in 1 second (or the power required to move 33,000 pounds 1 foot in 1 minute).

Kilowatts (kW)

Kilowatts (kW) is a metric that is often cited by European car manufacturers, as this is the EU’s standard measurement for engine power. A single kilowatt of engine power is the equivalent of approximately 1.34 BHP.

Torque of the engine is also measured with the kW metric (this refers to its turning power, or how hard it can push forward).

Other frequently used car metrics and tools

Whether you are ready to sell your car and make the switch to a newer model (or simply want to learn more about the automotive world), it is important to understand the various metrics that car manufacturers and journalists use.
