Enter the diameter of the tire into the calculator to determine the revolutions per mile of the bike or wheel.

## Rev Per Mile Formula

The following formula is used to calculate the total revs per mile of a bike tire.

RevPM =   63,360 / D * 3.14159
• Where RevPM is the revolutions per mile
• D is the diameter of the tire in inches

To calculate rev per mile, divide 63,360 by the diameter in inches, then multiply by pi.

## Rev Per Mile Definition

Rev per mile is short for revolutions per mile and is a measure of the total number of revolutions it takes a wheel of a certain size to travel a mile.
