1. What is the RPM to MPH Calculation?

The RPM to MPH calculation converts engine rotations per minute to miles per hour for a stationary bike, based on the wheel circumference. This helps simulate real cycling speed when using stationary exercise equipment.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( RPM \) — Engine rotations per minute
• \( Wheel\ Circumference \) — Distance traveled in one wheel rotation in miles
• \( 60 \) — Conversion factor from minutes to hours

Explanation: The equation calculates how many miles the wheel would travel in one hour at the given RPM, then converts it to miles per hour.

3. Importance of RPM to MPH Conversion

Details: This conversion is essential for stationary bike users who want to track their simulated speed and distance, allowing for more accurate workout metrics and performance tracking.

4. Using the Calculator

Tips: Enter engine RPM (typically between 60-120 rpm for cycling) and wheel circumference in miles. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure wheel circumference?
A: Measure the distance around the outside of your bike wheel (in miles) or convert from diameter using π × diameter.

Q2: What is a typical wheel circumference?
A: For a standard 700c road bike wheel, circumference is approximately 0.0014 miles (2.1 meters).

Q3: Why is this calculation important for stationary bikes?
A: It helps translate the mechanical effort into meaningful speed metrics that cyclists can relate to outdoor riding.

Q4: Does this work for all types of stationary bikes?
A: Yes, as long as you know the wheel circumference and can measure or input the RPM.

Q5: How accurate is this calculation?
A: It's mathematically precise for the given inputs, but actual road speed may vary due to factors like resistance and bike calibration.
