BHP to HP Calculator

This calculator uses the precise formula HP = BHP × 0.9863 to convert Brake Horsepower to Horsepower, 1000 BHP is equals to 986.30 HP.

Both units measure power, but they are used in different contexts. BHP is often used in the automotive industry to denote the power output of an engine without accounting for losses due to friction and other factors, while HP typically refers to the usable power at the wheels after these losses have been considered.

BHP to HP Conversion Formula

The conversion formula between BHP and HP can be expressed as:

BHP = HP × 1.01387

Conversely, to find HP from BHP:

HP = BHP × 0.9863

If an engine has a Brake Horsepower (BHP) of 150.

To convert it to Horsepower (HP):

HP = 150 BHP × 0.9863 HP = 147.945

An engine with 150 BHP would have an output of approximately 147.945 HP at the wheels.

How to Convert BHP to HP?

To convert Brake Horsepower to Horsepower, you can use the formula:

HP = BHP × 0.9863

Identify the BHP value: Let’s say you have an engine rated at 120 BHP.
Use the conversion factor: Multiply the BHP value by 0.9863.
Perform the calculation: HP = 120 × 0.9863 = 118.356 HP

HP = 10 × 0.9863 = 9.863 HP
HP = 360 × 0.9863 = 354.72 HP
HP = 1000 × 0.9863 = 986.32 HP
HP = 1200 × 0.9863 = 1183.58 HP

For an engine with a rating of 200 BHP:

HP = 200 × 0.9863 = 197.26 HP

A 200 BHP engine translates to approximately 197.26 HP.

Are hp and BHP the Same?

No, hp (Horsepower) and BHP (Brake Horsepower) are not the same. They are closely related, but they measure slightly different aspects of power output.

Brake Horsepower (BHP) is the measure of the actual power produced by an engine at the crankshaft, before any power losses in the drivetrain. It represents the engine’s true power output.

Horsepower (HP), on the other hand, is the measure of the power delivered at the wheels or output shaft, after accounting for the power losses in the drivetrain (transmission, differentials, etc.). HP is always lower than BHP due to these power losses.
