1. What is Knots to MPH Conversion?

Definition: This calculator converts wind speed measurements from knots to miles per hour (mph).

Purpose: It helps meteorologists, sailors, aviators, and weather enthusiasts understand wind speeds in different measurement systems.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ S_{mph} = S_{knots} \times 1.15078 \]

Where:

\( S_{mph} \) — Wind speed in miles per hour
\( S_{knots} \) — Wind speed in knots
1.15078 — Conversion factor (1 knot = 1.15078 mph)

Example: 30 knots × 1.15078 = 34.52 mph

3. Importance of Wind Speed Conversion

Details: Different industries use different units - aviation typically uses knots while public weather reports often use mph. Conversion ensures clear communication.

4. Using the Calculator

Tips: Enter the wind speed in knots (default 30). The calculator will automatically show the equivalent speed in mph.

5. Frequently Asked Questions (FAQ)
