1. What is FPS to MPH Conversion?

The FPS (feet per second) to MPH (miles per hour) conversion is used to translate speed measurements between these two common units. This is particularly useful in physics, engineering, and various sports applications.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

\[ MPH = FPS \times \left( \frac{3600}{5280} \right) \]

Where:

\( MPH \) — Miles per hour
\( FPS \) — Feet per second
3600 — Seconds in an hour (60 × 60)
5280 — Feet in a mile

Explanation: The formula converts feet to miles and seconds to hours, effectively multiplying by approximately 0.681818.

3. Practical Applications

Details: This conversion is commonly used in automotive testing, ballistics, aerodynamics, and sports science where speed measurements may be taken in different units.

4. Using the Calculator

Tips: Simply enter the speed in feet per second (FPS) and the calculator will automatically compute the equivalent speed in miles per hour (MPH).

5. Frequently Asked Questions (FAQ)

Q1: What is the exact conversion factor?
A: The exact conversion factor is 3600/5280 or approximately 0.681818.

Q2: How many MPH is 100 FPS?
A: 100 FPS is approximately 68.18 MPH (100 × 0.681818).

Q3: Why are different speed units used?
A: Different fields have traditional units - FPS is common in physics and engineering, while MPH is standard for vehicles in the US.

Q4: Can I convert MPH back to FPS?
A: Yes, divide MPH by 0.681818 or multiply by 1.46667 (the reciprocal).

Q5: Is this conversion used internationally?
A: Primarily in countries using imperial units. Most countries use meters/second or kilometers/hour.
