BHP and kilowatts are both units used to measure power, but they are used in different contexts and are based on different systems of measurement.
BHP
BHP stands for Brake Horsepower, and it is a unit of power used to measure the output power of engines, particularly internal combustion engines. Brake horsepower represents the power delivered by an engine to the output shaft, without accounting for any power losses due to auxiliary components like alternators, water pumps, and other accessories. It is essentially the power available at the engine’s crankshaft.
Kilowatts (kW)
Kilowatts are a unit of power used in the International System of Units (SI). One kilowatt is equal to 1000 watts. It is a standard unit for measuring electrical and mechanical power. Kilowatts are commonly used to quantify the power output of electrical devices, such as appliances, motors, and generators, as well as the power generation capacity of power plants.
How to convert BHP to kW
To convert Brake Horsepower (BHP) to kilowatts (kW), you can use the following simple formula:
kW = BHP × 0.7457
Here’s a step-by-step guide on how to perform the conversion:
- Step 1: Obtain the value of BHP that you want to convert to kilowatts.
- Step 2: Multiply the BHP value by the conversion factor 0.7457.
For Example – Convert 148 brake horsepower to kW
Ans. P(kW) = 0.745699872 × 148hp = 110.36 kW

FAQs on BHP to kilowatts conversion
What is 1 kilowatt in bhp?
To convert kilowatts (kW) to Brake Horsepower (BHP), you need to use the conversion factor, which is approximately 1 kW = 1.341 BHP. So, 1 kilowatt is approximately equal to 1.341 Brake Horsepower.
How do you convert bhp to kwh?
Converting Brake Horsepower (BHP) to kilowatt-hours (kWh) is not a direct conversion since BHP represents power (energy per unit of time), and kilowatt-hours represent energy. To convert BHP to kWh, you would need to know the time over which the power is applied. The formula to calculate energy in kilowatt-hours (kWh) is: Energy (kWh) = Power (kW) × Time (hours)
How much hp is 1 kWh?
Horsepower (hp) is a unit of power, and kilowatt-hours (kWh) are units of energy. They are not directly convertible, as horsepower represents the rate of doing work (power), whereas kilowatt-hours represent the total energy consumed or produced over time.
How much hp is 1 bhp?
HP and BHP both represent horsepower, and in the context of automotive or engine power, they are typically used interchangeably. So, 1 BHP is equal to 1 HP.
Is HP and BHP the same?
In the context of automotive or engine power, HP (Horsepower) and BHP (Brake Horsepower) are often used interchangeably. Both units represent the power output of an engine. However, there are slight technical differences in the way they are measured, which can lead to slightly different values. BHP is measured at the engine's crankshaft with all auxiliary components removed, while HP can be measured at various points in the drivetrain, considering power losses due to accessories. In practice, the difference between HP and BHP is often negligible.
How is BHP calculated?
Brake Horsepower (BHP) is typically measured using a dynamometer. The engine is connected to the dynamometer, which applies a load to simulate resistance. The engine is then run at its maximum power output, and the BHP is measured at the engine's crankshaft without any losses from auxiliary components. This provides an accurate measurement of the engine's power output.
