The Gear Ratio Calculator helps you determine the gear ratio, RPM, tire diameter, or MPH by inputting the known values. Gear ratio affects your vehicle's acceleration, fuel efficiency, and overall performance.

Using this calculator, you can find the optimal gear setup for your driving needs, whether for racing, towing, or everyday driving. Proper gear ratios help in achieving the desired balance between power and speed, improving the vehicle's performance and efficiency.

The formula for calculating the gear ratio involves multiplying the engine RPM by the tire diameter and then dividing by the product of the vehicle speed, the constant 336, and the transmission gear ratio.
