What is the formula to convert revolutions per minute [rpm] to kilometers per hour [km/h]?

The formula to convert an angular velocity expressed in revolutions per minute [rpm] to a linear velocity expressed in kilometers per hour [km/h] is given by:



Where:

•  is the linear velocity expressed in kilometers per hour (km/h)
•  is the angular velocity expressed in revolution per minute (rpm)
•  is the radius expressed in meters (m)
