This tool helps you convert revolutions per minute (RPM) to miles per hour (MPH) accurately and quickly.
How to Use the Calculator
This calculator determines the speed in miles per hour (MPH) from the given RPM (Revolutions Per Minute), wheel diameter, and gear ratio.
Instructions:
- Enter the diameter of the wheel in inches.
- Enter the gear ratio of your vehicle.
- Enter the RPM (Revolutions per Minute) of your engine.
- Click the “Calculate” button to get the results.
Results:
The results section displays various computed values:
- Wheel Diameter – The diameter of your wheel in inches.
- Gear Ratio – The gear ratio of your vehicle.
- RPM – The number of revolutions per minute.
- Wheel Circumference – The circumference of your wheel in inches.
- Speed (MPH) – The calculated speed in miles per hour.
Limitations:
Keep in mind the following limitations:
- Ensure all inputs are positive numbers.
- The accuracy of the result depends directly on the correctness of the given inputs.
- Wheel diameter should be in inches; gear ratio and RPM should be numeric and reflect realistic vehicle values.
