Compare calculators
Both calculators run independently β change the inputs on either side to compare results.
Engineering
Gear Ratio & Speed Calculator
Determine the gear ratio, output shaft speed, and torque multiplication of any meshing gear pair. Use it when designing drivetrains, gearboxes, or motor-to-wheel power transmissions.

Engineering
Gear Ratio & Speed Calculator
Calculates the output speed of a two-gear meshing pair given the driver and driven tooth counts and the input speed. Use it when selecting gear pairs for motors, gearboxes, or power-transmission drives. (For output torque, multiply input torque by the gear ratio R = drivenTeeth / driverTeeth and by mesh efficiency β see the explanation below.)
