RPM to Distance Formula

The following formula is used to calculate the RPM to Distance.

Drpm = RPM * pi*WD*T
  • Where Drpm is the RPM to Distance (inches)
  • RPM is the total rotations per minute (rpm) 
  • WD is the wheel diameter (inches) 
  • T is the time (min) 

To calculate distance from RPM, multiply the RPM by by pi times the wheel diameter times the time.

How to Calculate RPM to Distance?

The following example problems outline how to calculate RPM to Distance.

Example Problem #1

  1. First, determine the total rotations per minute (rpm).
    • The total rotations per minute (rpm) is calculated to be : 500.
  2. Next, determine the wheel diameter (inches).
    • The wheel diameter (inches) is measured to be: 3.5.
  3. Next, determine the time (min).
    • The time (min) is found to be: 1.5.
  4. Finally, calculate the RPM to Distance using the formula above: 

Drpm = RPM * pi*WD*T

The values given above are inserted into the equation below and the solution is calculated:

Drpm = 500 * pi*3.5*1.5 = 8246.68 (inches)

Example Problem #2

The variables needed for this problem are provided below:

total rotations per minute (rpm) = 300

wheel diameter (inches) = 2

time (min) = 30

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer. 

Drpm = RPM * pi*WD*T = (inches)
