This tool calculates the RPM based on the gear ratio to help you understand your engine’s performance.
RPM from Gear Ratio Calculator
This calculator helps you determine the wheel RPM based on the engine RPM, transmission ratio, final drive ratio, and tire diameter.
How to Use
- Enter the engine RPM in the first field.
- Enter the transmission ratio in the second field.
- Enter the final drive ratio in the third field.
- Enter the tire diameter in inches in the fourth field.
- Click the “Calculate” button to get the results.
Calculation Details
The wheel RPM is calculated using the formula:
wheel_RPM = (engine_RPM / (transmission_ratio * final_drive_ratio)) * (5280 / (tire_diameter * π / 12))
Limitations
This calculator provides a theoretical wheel RPM based on the inputs. Actual results may vary due to factors such as tire deformation, road conditions, and other mechanical inefficiencies.
