22+ Gear Ratio Calculator Teeth. Gear ratio is the relationship between the number of teeth on two meshing gears. Understand the relationship between gear teeth and rotational speeds.

Gear ratio = number of teeth on driven gear / number of teeth on driving gear. Here, you will learn how gear multiplies speed and torque using only a couple of simple mathematical formulas. Use this gear ratio calculator to quickly find the gear ratio between two gears based on their teeth count.
