The 2 gear rpm equation calculates the RPMs of a second gear when the RPMs and number of teeth are known for the first gear and the number of teeth of the second gear is known, gears.png             two gears  

INSTRUCTIONS: Choose units and enter the following:

  • (RPM1) Rotation rate of gear 1
  • (T1) Teeth in gear 1
  • (T2) Teeth in gear 2

Rotation Rate of Gear 2: The calculator returns 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 the relationship between interlocked gears and their revolution speed is: 

`RPM_1 * T_1 = RPM_2 * T_2`
