The 1/4 Mile HP Calculator is a valuable tool for automotive enthusiasts and engineers who want to determine critical performance metrics based on 1/4 mile drag racing data. Whether you are trying to find out the horsepower of a vehicle, its weight, or the time it takes to complete a 1/4 mile, this calculator simplifies the process with straightforward calculations.
Formula
The calculator uses the following formulas:
- To calculate Horsepower (HP): HP = (Weight / Time³) × 5.825
- To determine Weight (W) given HP and Time (T): W = (HP × Time³) / 5.825
- To find Time (T) with given Weight (W) and HP: T = (W / (HP × 5.825))^(1/3)
How to Use
- Enter the weight of the vehicle, time to complete the 1/4 mile, or horsepower into the respective fields.
- Click the “Calculate” button.
- The result will display the calculated value for the missing parameter based on the provided inputs.
Example
For example, if you know a vehicle weighs 3,000 pounds and completes the 1/4 mile in 12 seconds, you can use the calculator to find the horsepower. Enter 3,000 pounds for weight and 12 seconds for time, and the calculator will compute the horsepower as follows:
- Calculated Horsepower (HP) = (3000 / 12³) × 5.825 = 180.52 HP (approximately).
