Quarter Mile Calculator

    You can use this quarter mile calculator to determine the terminal speed (trap speed) and quarter-mile elapsed time (ET) of a vehicle based on its weight and power.
  • Choose which unit system of measurement you need from the drop-down menu
  • Choose which equation you would like to use to calculate the terminal speed at the end of the quarter-mile and the quarter-mile ET .
  • Enter the total weight of both the vehicle and the driver.
  • Click on the "Calculate" button to generate the calculation.

  • Quarter-Mile Performance

    When estimating quarter-mile performance, some key variables should be taken into consideration. These include driver skill, fuel type, temperature, gearing, humidity, and drivetrain power loss.
    To achieve an optimal quarter-mile time, a launch is imperative. If the launch is executed at a high rpm, the vehicle will suffer a loss of traction.
