Gear Calculator - Sariel Gear Box is a useful tool for calculating the final ratio of gears and the number of motors to produce a desired output (speed and torque). It is a very versatile and accurate tool. It allows you to calculate the final ratio of up to 10 pairs of gears.

You can choose between two types of calculations: one in which you can choose a single or multiple output and the other in which you can choose one or multiple input values. In the first case, you need to select one or more motors for which you want to calculate the output.
