This 1/8 Mile to 1/4 Mile conversion calculator is used to calculate the approximate time taken by a vehicle to run in a quarter mile (402.336 meter or 0.25 mile) track based on elapsed time taken by the same vehicle to reach eighth mile (201.168 meter or 0.125 mile) track. But the time may vary for different vehicles based on the running speed. Enter the time taken to complete the eighth mile track (1/8) and calculate the quarter mile (1/4) time.
A vehicle runs in a 1/8 miles track at 15 seconds. How much time (elapsed time) will it take to complete 1/4 mile track?
= (1/8 Mile ET + .22) / .655
= (15 + 0.22) / .655
1/4 Mile ET = 23.2366
