BHP to kW Conversion Calculator

Easily convert BHP (Brake Horsepower) to kW (kilowatts) with our online calculator. Simply input BHP to get the equivalent value in kilowatts for power calculations. Brake Horsepower (BHP) measurement needs the input of the BHP value along with the standard conversion factor to obtain kilowatts (kW). Engine or motor power output at crankshaft or flywheel is measured as BHP, which detection occurs before mechanical parts and friction result in power loss; thus, this method is extensively used in automotive and mechanical industries. Kilowatts (kW) function as a power measurement unit for electrical engineering work as well as international power system applications. A BHP value converted to kW requires multiplication by the constant factor 0.7457. The conversion relationship between units becomes 1 BHP equals 0.7457 kW. You can obtain 7.457 kilowatts from your 10-horsepower base. A universal power comparison method that allows for analyzing engine potentials between different units establishes uniform power evaluation standards as well as supporting multi-national efficiency evaluation needs through standardized performance data analysis. This conversion rule enables engineers and automotive specialists and electrical engineers to convert between imperial and metric units in their applications.

Conversion using the Brake Horsepower to kilowatts Calculation Formula

The formula to convert Brake Horsepower (BHP) to Kilowatts (kW) is:

This formula can be used in various contexts, including:

KW = BHP × 0.7457

For Example, If you have 10 BHP, the conversion to kW would be:

kW = 10 × 0.7457 = 7.457kW

Where:

BHP (Brake Horsepower) is a measure of the engine's output power, excluding losses from the drivetrain.
kW (Kilowatts) is a metric unit of power commonly used in many countries.

BHP to kW Conversion Formula | Brake Horsepower to Kilowatts

The conversion between brake horsepower (BHP) and kilowatts (kW) occurs exclusively during power measurements of engine and mechanical system outputs:

The power measurement method for engines that exists before driveline parts create energy loss is brake horsepower (BHP). The basic engine power appears directly from the crankshaft or flywheel measurement process.
The international power measurement standard is kilowatts (kW) that engineers use across the globe specifically for electrical and engineering applications. The International System of Units (SI) recognizes it as their standard power measurement unit.
