1. What is RPM to FPS Conversion?

The RPM to FPS conversion calculates the linear speed in feet per second (FPS) of a bike based on its rotational speed (RPM) and wheel diameter. This is useful for cyclists and engineers to understand the actual speed of the bike.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( RPM \) — Rotations per minute (rev/min)
• \( \pi \) — Mathematical constant Pi (approximately 3.1416)
• \( wheel\_diameter \) — Diameter of the wheel (inches)

Explanation: The formula converts rotational speed to linear speed by calculating the circumference of the wheel and adjusting for time units.

3. Importance of FPS Calculation

Details: Calculating FPS from RPM helps in determining the actual speed of the bike, which is crucial for performance analysis, gear ratio optimization, and safety considerations.

4. Using the Calculator

Tips: Enter RPM in revolutions per minute and wheel diameter in inches. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why convert RPM to FPS?
A: Converting RPM to FPS helps understand the actual linear speed of the bike, which is more intuitive than rotational speed.

Q2: What is a typical RPM for cycling?
A: Typical cycling RPM ranges from 60 to 100 RPM, depending on the cyclist's preference and conditions.

Q3: How does wheel diameter affect FPS?
A: Larger wheel diameters result in higher FPS for the same RPM, as the circumference is larger.

Q4: Can this calculator be used for other vehicles?
A: Yes, this formula applies to any wheeled vehicle where RPM and wheel diameter are known.

Q5: What are limitations of this calculation?
A: This calculation assumes no slippage and perfect rolling conditions. Actual speed may vary due to factors like tire pressure and surface conditions.
