Enter the distance covered, vehicle’s speed, and vehicle’s acceleration into the calculator to determine the Drag Time. This calculator can also evaluate any of the variables given the others are known.

Drag Time Formula

The following formula is used to calculate the Drag Time.

DT = D / (V * sqrt((2 / A)))


  • DT is the Drag Time (seconds)
  • D is the distance covered (meters)
  • V is the vehicle’s speed (meters/second)
  • A is the vehicle’s acceleration (meters/second^2)

To calculate the Drag Time, divide the distance covered by the product of the vehicle’s speed and the square root of twice the vehicle’s acceleration.

What is a Drag Time?

Drag Time is a term used in the field of motorsports, specifically in drag racing, to refer to the time it takes for a vehicle to complete a specific distance, usually a quarter-mile, from a standing start. It is a measure of the vehicle’s acceleration and speed, and is used to compare the performance of different vehicles. The lower the drag time, the faster the vehicle.

How to Calculate Drag Time?

The following steps outline how to calculate the Drag Time using the given formula:

  1. First, determine the distance covered (D) in meters.
  2. Next, determine the vehicle’s speed (V) in meters per second.
  3. Next, determine the vehicle’s acceleration (A) in meters per second squared.
  4. Next, substitute the values of D, V, and A into the formula: DT = D / (V * sqrt((2 / A))).
  5. Finally, calculate the Drag Time (DT).
  6. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge:

Distance covered (D) = 500 meters

Vehicle’s speed (V) = 20 meters per second

Vehicle’s acceleration (A) = 4 meters per second squared
