This calculator will help you convert brake horsepower (BHP) to wheel horsepower (WHP) quickly and easily.
How to Use the BHP to WHP Calculator
Enter the following values in the provided input fields:
- Brake Horsepower (BHP): The total power produced by your vehicle’s engine before losses.
- Drivetrain Loss (%): The percentage of power loss due to the drivetrain.
- Other Factors (%): Any other percentage factors that might affect the power loss.
Once you have entered the values, click on the “Calculate” button to see your results. The calculator will show a table including the BHP, Drivetrain Loss percentage, Other Factors percentage, and the resultant Wheel Horsepower (WHP).
Explanation of Calculations
The Wheel Horsepower (WHP) is calculated by considering all the losses from the Brake Horsepower (BHP). The formula used is:
WHP = BHP * (1 - (TotalLossPercent / 100))
TotalLossPercent is the sum of the Drivetrain Loss percentage and Other Factors percentage. The resultant WHP is the power that is actually delivered to the wheels of the vehicle.

Use Cases for This Calculator
Determining Vehicle Horsepower Upgrade
If you’re considering upgrading your vehicle’s engine, understanding the difference between brake horsepower (BHP) and wheel horsepower (WHP) is crucial. By calculating WHP from the BHP ratings, you can better evaluate how much additional power the modifications you plan to install will provide at the wheels, ultimately enhancing your driving experience.
Comparing Performance Between Vehicles
You might be in the market for a new car and want to compare the performance metrics of various models. Using the BHP to WHP calculator, you can accurately assess how different engines translate their power to the wheels, allowing you to make more informed decisions about your purchase.
Optimizing Engine Performance After Modifications
After making performance upgrades to your engine, it’s essential to know how these changes impact overall power delivery. By inputting the new BHP values into the calculator, you can ascertain the resultant WHP and fine-tune your modifications for optimal performance.
Understanding Power Loss in Drivetrains
Every vehicle experiences some power loss through the drivetrain, affecting how BHP translates to WHP. By utilizing the calculator, you can gain insights into how much power is lost, thereby understanding the efficiency of your vehicle’s architecture and making informed modifications if necessary.
Evaluating Tuning Options
If you’re contemplating tuning your vehicle’s engine, knowing the effective WHP can significantly influence your decision. By calculating WHP from the BHP figures, you can weigh the benefits of different tuning options against the anticipated gains in power at the wheels, helping you achieve your performance goals.
Preparing for Drag Racing Events
For drag racers, knowing the WHP of your vehicle could be the difference between winning and losing a race. The BHP to WHP calculator enables you to predict how your vehicle will perform under race conditions, allowing for better strategies when competing against others.
Planning Engine Builds for Project Cars
If you’re building a project car, understanding the relationship between BHP and WHP can guide your design decisions. Inputting expected BHP numbers into the calculator gives you a clearer picture of how power will be transmitted to the wheels, helping you select the right components.
Assessing Fuel Efficiency with Power Changes
When modifying vehicles to increase horsepower, many overlook the impact on fuel efficiency. By calculating WHP after determining your new engine’s BHP, you can better analyze how improved performance may affect your car’s mileage, helping you strike a balance between power and economy.
Resolving Performance Issues
Experiencing a lack of power in your vehicle can be frustrating, and calculating WHP can help diagnose the issue. By comparing the actual WHP to expected figures derived from BHP, you can identify whether the problem lies in engine efficiency or drivetrain loss, facilitating accurate troubleshooting.
Educating New Vehicle Owners
If you’re a newly licensed driver or a vehicle enthusiast, learning about BHP and WHP can be enlightening. Using the BHP to WHP calculator helps demystify automotive performance metrics, providing essential knowledge as you explore the world of cars and engines, making you more informed as a driver.
