How the Gear Ratio RPM Speed Calculator Works

This calculator uses a standard formula that relates engine RPM, gear ratio, tire diameter, and speed:

Speed = (RPM × Tire Diameter) / (Gear Ratio × Constant)

Where:

• RPM = Engine revolutions per minute
• Gear Ratio = Transmission or differential ratio
• Tire Diameter = Diameter of the tire
• Constant = Unit conversion factor
