# WHP to HP Calculator

The calculator will convert wheel horsepower to engine horsepower &amp; vice versa.

WHP to HP
HP to WHP

Our WHP to Hp calculator helps to find the engine horsepower that is equivalent to the wheel horsepower. Also, you may get reverse conversions from HP to WHP with this tool.

## WHP vs HP:

HP is the actual power of the vehicle’s engine. While on the other hand, WHP refers to the horsepower delivered to the wheel when the automobile is moving. Our smart WHP to HP converter readily performs to and fro conversions song both of these powers and saves you a lot of time.

• The actual difference between both terms is about 20 - 45%

## WHP To BHP Formula:

Our calculator uses the following equations to perform to and fro conversions among WHP and HP:

### WHP To HP Conversion:

HP = WHP / (1 – DL )

Where;

DL = Drive train loss

### HP To WHP Conversion:

WHP = EHP / DTLF

Where;

DTLF = Drive train loss factor

## Example:

If the wheel horsepower of a car is 240, then what is the actual engine horsepower delivered to the wheel?

### Solution:

HP = WHP / (1 – DL )

HP = 240/ (1 – 35)

HP = -240/34

HP = -7.05

The negative indicates the horsepower is applied to the wheel in the opposite direction.

## Drive Train Loss Chart:

 Front Wheel Drive 10% (0.10) Rear Wheel Drive 15% (0.15) Overall Wheel Drive 25% (0.25)

## Working of WHP To HP Calculator:

Our calculator functions to provide you with accurate conversions among wheel and engine horsepower. Its simple UI lets you enter the following inputs to get results:

Inputs:

• Select the conversion type
• Enter the required value according to your selection (Either EHP or HP)
• Tap Calculate

Output:

• WHP to HP conversion
• HP to WHP conversion
