Enter the velocity of an object and the diameter of the wheel into the calculator to determine the RPM (revolutions per minute).

Velocity to RPM Formula

The following formula is used to convert velocity to RPM.

RPM = frac{V}{pi times D} times 60

Variables:

  • RPM is the revolutions per minute
  • V is the velocity (meters per second)
  • D is the wheel diameter (meters)

To convert velocity to RPM, divide the velocity by the product of pi and the wheel diameter, then multiply the result by 60.

What is RPM?

RPM stands for revolutions per minute, and it is a unit of rotational speed or the frequency of rotation around a fixed axis. It measures the number of complete turns a wheel or another object makes in one minute. It is a common unit used in various applications, including automotive, engineering, and industrial machinery.

How to Calculate RPM from Velocity?

The following steps outline how to calculate the RPM from velocity.

  1. First, determine the velocity (V) in meters per second.
  2. Next, determine the wheel diameter (D) in meters.
  3. Next, gather the formula from above = RPM = (V / (π × D)) × 60.
  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.

velocity (V) = 15 meters per second

wheel diameter (D) = 0.5 meters
