What does Brake Horsepower (BHP) mean?
Brake horsepower (BHP) is the unit of power measurement used to denote the actual power output of an engine before the loss of power caused by the gearbox, alternator, differential, and other auxiliary components. It's measured directly from the engine's output shaft, providing a more accurate figure of an engine's power than horsepower measurements that include drivetrain losses.

What are Kilowatts (kW)?
Kilowatts (kW) are a unit of power in the International System of Units (SI), representing one thousand watts of power. It is widely used around the world for a variety of applications, including electrical, mechanical, and thermal power output measurements. In the context of automotive engines, kW is increasingly being used as a standard measure of engine power, especially in countries and regions where the metric system is the norm.
How do you convert BHP to kW?
To convert BHP to kW, multiply the BHP value by 0.7457. This conversion factor is derived from the definition that 1 horsepower equals 745.7 watts, and since 1 BHP is equivalent to 1 HP for conversion purposes, the same factor applies.
How many kW in 1 BHP?
There are approximately 0.7457 kilowatts in 1 brake horsepower.
BHP to kW Formula
The formula to convert BHP to kW is: kW = BHP x 0.7457
For example, if you have an engine with 300 BHP, the equivalent power in kilowatts would be: kW = 300 x 0.7457 = 223.71 kW
