How to Calculate Gear Ratio?
Gear Ratio calculator uses Gear Ratio = Radius of Pitch Circle of Wheel/Radius of Pitch Circle of Pinion to calculate the Gear Ratio, Gear ratio is the ratio of the number of teeth in the gear to the number of teeth in the pinion, the pinion being the smaller of the two gears in mesh. Gear Ratio is denoted by G symbol.
