M/Min To Rpm Formula

RPM = (M/Min) / (πD)

What is M/Min To Rpm?

M/Min to RPM is a conversion from meters per minute to revolutions per minute. This is often used in mechanical engineering to measure the speed of rotation of a mechanical component. Meters per minute measures linear speed, or how fast an object is moving in a straight line, while revolutions per minute measures rotational speed, or how fast an object is spinning around an axis. The conversion between these two units of speed depends on the circumference of the rotating object.

How to Calculate M/Min To Rpm?

The following steps outline how to calculate the RPM (Revolutions Per Minute) using the formula RPM = (M/Min) / (πD).


  1. First, determine the speed in meters per minute (M/Min).
  2. Next, determine the diameter of the rotating object (D) in meters.
  3. Next, gather the formula from above = RPM = (M/Min) / (πD).
  4. Finally, calculate the RPM (Revolutions Per Minute).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Speed in meters per minute (M/Min) = 120

Diameter of the rotating object (D) in meters = 0.5
