M/Min to RPM Calculator

Formula

The formula to calculate RPM is:

RPM = $\frac{M/Min}{\pi D}$

Where:

RPM is the speed in revolutions per minute
M/Min is the speed in meters per minute
$\pi$ is the mathematical constant Pi, approximately equal to 3.14159
D is the diameter of the rotating object (meters)

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.

Example Calculation

Example 1:

Speed: 100 meters per minute
Diameter: 0.5 meters

Calculation:

RPM = $\frac{100}{\pi \times 0.5} = \frac{100}{1.5708} \approx 63.66$ revolutions per minute

Example 2:

Speed: 200 meters per minute
Diameter: 1 meter

Calculation:

RPM = $\frac{200}{\pi \times 1} = \frac{200}{3.14159} \approx 63.66$ revolutions per minute
