1. What is a Speed of Light Calculator in Miles per Hour?

Definition: This calculator converts the speed of light from meters per second (m/s) to miles per hour (mph) using a conversion factor.

Purpose: It helps physicists, students, and science enthusiasts understand the speed of light in more familiar units.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( v \) — Speed of light in miles per hour (mph)
• \( c \) — Speed of light in meters per second (m/s)
• \( \text{Conversion\_factor} \) — Conversion factor from m/s to mph (2.236936)

Explanation: The speed of light in m/s is multiplied by the conversion factor to get the equivalent speed in mph.

3. Importance of Speed of Light Conversion

Details: Converting fundamental constants to different units helps in scientific communication and makes abstract concepts more relatable.

4. Using the Calculator

Tips: Enter the speed of light in m/s (default 299,792,458) and the conversion factor (default 2.236936). All values must be > 0.
