The Belt Pulley RPMs calculator computes the RPMs of a pulley based on the belt speed (bS) and diameter (D) of the pulley.BeltSpeed-illustration.pngBelt

INSTRUCTIONS: Choose units and enter the following:

  • (bS) This is the linear speed of the belt
  • (D) This is the diameter of the pulley.

Pulley RPMs: The calculator return the rotation rate in revolutions per minute. However this can be automatically converted to compatible units via the pull-down menu.

The Math / Science

The formula for belt pulley RPMs is

   RPM  = bS / (π • D)
