Brake horsepower (BHP) and horsepower (HP) are often used interchangeably, but there’s a small difference. BHP measures the engine’s power before losses like the gearbox or accessories, while HP can sometimes refer to power at the wheels or other points.
Power Converter
300 BHP = 300.0 HP HP
How to Convert BHP to HP
In most cases, BHP and HP are very close, so the conversion is straightforward:
HP ≈ BHP
However, if you want to estimate wheel horsepower from BHP, you can account for drivetrain losses (usually around 10-15%).
Example Calculation
If your engine produces 250 BHP and you assume a 15% drivetrain loss, then:
HP = 250 × (1 - 0.15) = 212.5 HP
This means about 212.5 horsepower reaches the wheels.
Why This Matters
Knowing the difference between BHP and HP helps you understand where power is measured and what your car actually delivers. Use this calculator to get a quick and clear idea of your engine’s true power.
