`RPM_2 = `

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, ** two gears **

**INSTRUCTIONS:** Choose units and enter the following:

- (
**RPM**) Rotation rate of gear 1_{1} - (
**T**) Teeth in gear 1_{1} - (
**T**) Teeth in gear 2_{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`
