**Quarter Mile Calculator: **Understanding and solving quarter-mile problems is not easy as
having a piece of cake. But our free 1/4 Mile ET Calculator does make all the calculations and produces
the result with a detailed explanation. Find the formulas of Huntington's quarter-mile ET and speed,
Fox's quarter-mile ET and speed, and Hale's quarter-mile ET and speed, step by step process, and solved
examples in the below-mentioned sections.

By following the below points, you can easily find the quarter-mile elapsed time and quarter-mile speed.

- Find the weight and power mentioned in the question.
- Divide weight by power and apply 1/3 power of the result.
- Multiply the result by 6.29 to get Huntington's quarter-mile ET.
- Multiply the result in step 2 by 224 to get Huntington's quarter-mile speed.
- Find the product of result in step 2 by 6.269 to check Fox's quarter-mile ET
- Find the product of result in step 2 by 230 to check Fox's quarter-mile speed
- Multiply the result in step 2 by 5.825 to find Hale's quarter-mile ET.
- Multiply the result in step 2 by 234 to find Hale's quarter-mile speed.

The quarter-mile is one of the performance estimators of a vehicle. Quarter-mile is also called 1/4 Mile. It calculates quarter-mile ET and final speed using the power and weight of the vehicle. We have three different types to measure vehicle performance. Those are Huntington's quarter-mile, Fox's quarter-mile, Hale's quarter-mile. The formulas to calculate the quarter-mile ET and final speed are here.

Huntington's quarter-mile ET = 6.290 * (weight / power)¹ᐟ³

Huntington's quarter-mile speed = 224 * (weight / power)¹ᐟ³

Fox's quarter-mile ET = 6.269 * (weight / power)¹ᐟ³

Fox's quarter-mile speed = 230 * (weight / power)¹ᐟ³

Hale's quarter-mile ET = 5.825 * (weight / power)¹ᐟ³

Hale's quarter-mile speed = 234 * (weight / power)¹ᐟ³

Where,

ET is the elapsed time over a quarter-mile distance

weight is the total weight of the vehicle

power is the peak engine power at the clutch

**Example**

**Question: A car that weighs 6100 kgs run on a quarter-mile track has wheel horse power as 300.
Calculate 1/4 mile ET, final speed.**

**Solution:**

Given that

Weight of car = 6100 kgs

power = 300

Quarter-mile ET = 6.290 * (weight / power)¹ᐟ³

= 6.290 * (6100/300)¹ᐟ³

= 6.290 * (20.033)¹ᐟ³

= 6.290 * 2.729

= 17.16

Quarter-mile final speed = 224 * (weight / power)¹ᐟ³

= 224 * (6100/300)¹ᐟ³

= 224 * 2.729

= 611.29

Therefore, 1/4 mile ET is 17.16, 1/4 final speed is 611.29.

**1. How to use 1/4 mile calculator?**

A quarter-mile calculator is used to compute the drag race of a vehicle. Enter the vehicle weight and power in the input fields of the online calculator and press on the calculate to check the vehicle speed and ET.

**2. Calculate the quarter-mile elapsed time of a vehicle that weighs 3500 kgs
with a wheel horsepower of 290.**

Initial velocity means the velocity of an object before it has 1/4 mile or quarter-mile is a drag race or a motorcycle race that compete to come first to cross the finish line from the starting. ET is the elapsed time is the time taken to complete the race.

**3. What is 1/4 mile ET mean?**

Quarter mile ET = 5.825 x (3500/290)¹ᐟ³

= 5.825 x (12.068)¹ᐟ³

= 5.825 x 2.29

= 13.36

**4. Which website provides the best tool to calculate quarter-mile ET,
quarter-mile speed?**
