What is the Kilowatts to Brake Horsepower Converter?
The Kilowatts (kW) to Brake Horsepower (BHP) converter translates the pure electrical or metric energy of an engine back into the standard mechanical rating used by auto manufacturers and dyno tuners.
How It Works (Formula)
Because a Kilowatt (1,000 Watts) is roughly 34% more powerful than a single Mechanical Horsepower (745.7 Watts), the calculator must use division to scale the number up. It divides the total Kilowatts by the constant 0.745699872 to find the exact BHP.
$$ P_{(\text{BHP})} = \frac{P_{(\text{kW})}}{0.745699872} $$
The standard mechanical division formula for internal combustion engines.
How to Use It
Enter the power rating of the motor or engine in Kilowatts (kW). The tool will instantly divide that value by 0.745699 and output the raw crankshaft power in Brake Horsepower (BHP). For example, a 150 kW motor equates to 201.1 BHP.
