# How To Calculate Revolutions per Minute (RPM)?

Short tutorial that explains you on how to calculate the Revolutions per Minute (RPM).

## Rotational Speed Measurement

Revolutions Per Minute (RPM) is a measure of number of revolutions completed in one minute around a fixed axis, giving the speed of a mechanical component. RPM is generally used in Mechanical Engineering to describe the performance of automobile engines. RPM is used to determine the rotational speed of an engine.

It is the unit of measurement of revoultions per minute / rotations per minute made by an engine. There were no specific formula to calculate the Revoultions Per Minute (RMP).

In this short tutorial, you are explained how to calculate Revolutions Per Minute (RPM) of an engine theoretically.

Step 1:
Put a mark on the motor engine on its rotating part.
Step 2:
Have a timer in hand.
Step 3: Switch ON the motor engine.
Step 4: Start counting the number or revolutions or rotations that a motor engine makes with reference to the mark you created.
Step 5: When the timer reaches 1 Minute, Switch OFF the motor engine.
Step 6: Now, the count you calculated is the number of revolutions per minute (rpm) made by the engine.
