1. What is the MPH Conversion?

The MPH (Miles Per Hour) conversion calculates speed when you know the distance traveled in kilometers and the time taken in hours. It converts the metric speed measurement (km/h) to imperial units (mph).

2. How Does the Calculator Work?

The calculator uses the MPH formula:

\[ MPH = \frac{km}{hours} \times 0.621371 \]

Where:

\( km \) — Distance traveled in kilometers
\( hours \) — Time taken in hours
\( 0.621371 \) — Conversion factor from km to miles

Explanation: First calculates km/h, then converts kilometers to miles using the standard conversion factor.

3. Importance of Speed Conversion

Details: Essential for understanding speed measurements in different unit systems, particularly when traveling between countries or working with international transportation data.

4. Using the Calculator

Tips: Enter distance in kilometers and time in hours. Both values must be positive numbers. For partial hours, use decimals (e.g., 1.5 hours for 1 hour 30 minutes).

5. Frequently Asked Questions (FAQ)

Q1: Why 0.621371 conversion factor?
A: This is the exact conversion factor from kilometers to miles (1 km = 0.621371 miles).

Q2: How to convert minutes to hours?
A: Divide minutes by 60 (e.g., 30 minutes = 0.5 hours).

Q3: What's the difference between km/h and mph?
A: 1 mph equals approximately 1.60934 km/h. Mph is used in the US and UK, while km/h is standard in most other countries.

Q4: Can I use this for running/walking pace?
A: Yes, it works for any speed calculation where you know distance and time.

Q5: How accurate is this conversion?
A: The calculation is mathematically exact when using the precise conversion factor.
