1/4 Mile HP:

The 1/4 mile horsepower calculator is used to determine the horsepower of a vehicle based on its weight and the time it takes to complete a 1/4 mile run. This metric is crucial for evaluating the performance and power-to-weight ratio of vehicles in automotive and racing contexts.

## Formula

The 1/4 mile horsepower (HP1/4HP_{1/4}HP1/4​) can be calculated using the following formula:

HP1/4=(WHP1/3)×5.825HP_{1/4} = \left( \frac{W}{HP^{1/3}} \right) \times 5.825HP1/4​=(HP1/3W​)×5.825

where:

• HPHPHP is the horsepower of the vehicle.
• WWW is the weight of the vehicle in pounds.
• TTT is the time taken to cover 1/4 mile in seconds.

## How to Use

To use the 1/4 Mile HP Calculator:

1. Enter the vehicle’s horsepower (HPHPHP) in horsepower units.
2. Enter the vehicle’s weight (WWW) in pounds.
3. Enter the 1/4 mile time (TTT) in seconds.
4. Click the “Calculate” button.
5. The calculated 1/4 mile horsepower (HP1/4HP_{1/4}HP1/4​) will be displayed.

## Example

Suppose a vehicle has a horsepower of 400 HP, weighs 3500 lbs, and completes the 1/4 mile in 12 seconds. Using the calculator:

1. Enter 400 in the HP field.
2. Enter 3500 in the weight field.
3. Enter 12 in the time field.
4. Click “Calculate.”
5. The 1/4 mile horsepower is calculated as approximately 208.65 HP.
