About BHP to kW Conversion

What is BHP and kW?

BHP (Brake Horsepower) and kW (Kilowatt) are both units used to measure power, particularly in the context of engines and motors.

• BHP (Brake Horsepower): A unit of power commonly used in the automotive industry, especially in the UK and some other countries. It represents the power output of an engine without the loss in power caused by the gearbox, generator, differential, water pump, and other auxiliary components.
• kW (Kilowatt): The standard unit of power in the International System of Units (SI). One kilowatt is equal to 1,000 watts and is commonly used to measure electrical power, motor power, and the rate of energy transfer.

Formula for BHP to kW Conversion

The formula to convert BHP to kW is:

\[kW = BHP \times 0.745699872\]

Where:

• \(kW\) is the power in kilowatts
• \(BHP\) is the power in brake horsepower
• \(0.745699872\) is the conversion factor

Calculation Steps

1. Identify the power in BHP.
2. Multiply the BHP value by 0.745699872.
3. The result is the equivalent power in kW.

Example

Let's convert 100 BHP to kW:

1. Given: BHP = 100
2. Apply the formula: \(kW = 100 \times 0.745699872\)
3. Calculate: \(kW = 74.5699872\)
4. Rounding to 2 decimal places: \(kW \approx 74.57\)

Visual representation:

Therefore, 100 BHP is equivalent to approximately 74.57 kW.
