RPM to Linear Velocity

The Linear Velocity from RPMs calculator computes the linear velocity based on the rotation rate (R) and the diameter of the wheel (D).

Calculate Linear Velocity from RPMS:

1. Choose units
2. Enter the rotation rate (R)
3. Enter the outer diameter (D)

Linear Velocity (V): The calculator returns velocity in meters per second.  However, this can be automatically converted to other velocity units via the pull-down menu.

The Math

The Linear Velocity from RMPs can be found using the following formula: 

    `v=(2pi)/60*r*N` 

where:

• v = linear velocity on the edge of the radius (e.g. pulley) 
• r = radius, where radius is half the diameter
• N = number of revolutions per minute
