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.

## Rev Per Mile Example

How to calculate a rev per mile?

**First, measure the tire diameter.**Measure the tire diameter in inches.

**Next, calculate the circumference.**Calculate the circumference by multiplying the diameter by pi.

**Finally, calculate the rev per mile.**Calculate the number of revolutions per mile by dividing 63,360 by the tire circumference.

## FAQ

**How many revolutions does my bike take to go one mile?**

The amount of revolutions it takes a bike to travel a mile depends on the size of the wheel. The larger the wheel the lower the revolutions.
