1. What is a Speed To MPH Calculator?

Definition: This calculator converts speed from various units to miles per hour (mph) using a conversion factor.

Purpose: It helps convert speed measurements between different units for transportation, sports, or scientific applications.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ S_{mph} = S \times CF \]

Where:

\( S_{mph} \) — Speed in miles per hour
\( S \) — Original speed measurement
\( CF \) — Conversion factor to mph

Explanation: The original speed is multiplied by the appropriate conversion factor to get the equivalent speed in mph.

3. Importance of Speed Conversion

Details: Accurate speed conversion is essential for international travel, vehicle specifications, sports performance tracking, and scientific research.

4. Using the Calculator

Tips: Enter the original speed value and the appropriate conversion factor (default 0.621371 for km/h to mph). All values must be > 0.
