# WHP to HP Calculator

## WHP to HP Calculator

Enter either WHP or HP and select Drive Train to calculate the missing horsepower.

The **WHP to HP Calculator** helps you convert Wheel Horsepower (WHP) to Engine Horsepower (HP) and vice versa. This conversion is crucial because drivetrain losses cause the power measured at the wheels (WHP) to be less than the power produced by the engine (HP).

### Formula

The formula to convert WHP to HP is:

To convert HP to WHP, the formula is:

**Variables:**

Variable | Description |
---|---|

WHP | Wheel Horsepower |

HP | Engine Horsepower |

Drive Train Loss | The efficiency factor of the drivetrain |

### Calculation Examples

#### Example 1

**WHP**: $300$**Drive Train**: Rear Wheel ($0.85$)

**Step-by-Step Calculation**:

- Identify the values: WHP = 300 and Drive Train Loss = 0.85.
- Calculate the Engine HP: $HP=\frac{300}{0.85}\approx 352.94$.

**Result**: The Engine Horsepower is approximately $352.94$ HP.

#### Example 2

**HP**: $400$**Drive Train**: All Wheel ($0.80$)

**Step-by-Step Calculation**:

- Identify the values: HP = 400 and Drive Train Loss = 0.80.
- Calculate the Wheel Horsepower: $WHP=400\times 0.80=320$.

**Result**: The Wheel Horsepower is $320$WHP.
