BHP to Speed Calculator

Calculate Speed from BHP and Weight



Formula

The formula to calculate the speed (S) is:

\[ S = \sqrt{\frac{BHP \times 375}{W}} \]

Where:

What is BHP?

BHP, or brake horsepower, is a unit of measurement for the power output of an engine. It is measured at the engine’s output shaft and represents the engine’s power without any losses due to the gearbox, alternator, differential, water pump, and other auxiliary components. BHP is a critical factor in determining a vehicle’s performance, as it directly influences the vehicle’s speed and acceleration capabilities.

Example Calculation

Let's assume the following values:

Using the formula:

\[ S = \sqrt{\frac{300 \times 375}{4000}} \approx 8.37 \text{ mph} \]

The speed (\(S\)) is approximately 8.37 mph.
