Enter your elapsed time (ET) value and then select the conversion type (1/8 mile to 1/4 mile or 1/4 mile to 1/8 mile) and click “Convert” to obtain the converted estimated time!
Use our 1/8 mile to 1/4 mile calculator to easily convert drag racing distances. Determine the equivalent quarter-mile time based on the eighth-mile result. Skip to content
This calculator uses mathematical estimations to convert the 1/8 mile time and speed into an approximate 1/4 mile time. It uses a formula based on average racing data, assuming consistent acceleration: Time(1/4 mile) = Time(1/8 mile) * 1.55. Please note, this formula provides a general estimate.
This calculator approximates your 1/4 mile time based on the inputted 1/8 mile time and speed. The quarter mile time is estimated using a multiplication factor of 1.5 on the 1/8 mile time. The speed is estimated by adding 25% of the 1/8 mile speed to the original speed.
