1. What is a Knots to MPH Calculator?

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

Purpose: It helps mariners, aviators, and weather professionals convert between these common speed units.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The speed in knots is multiplied by the conversion factor to get the equivalent speed in miles per hour.

3. Importance of Speed Conversion

Details: Accurate speed conversion is crucial for navigation, aviation, weather reporting, and maritime operations where different units are standard.

4. Using the Calculator

Tips: Simply enter the speed in knots and the calculator will automatically compute the equivalent speed in miles per hour.

5. Frequently Asked Questions (FAQ)

Q1: What is a knot in speed measurement?
A: One knot equals one nautical mile per hour, approximately 1.15078 statute miles per hour.

Q2: Why is the conversion factor 1.15078?
A: This factor comes from the ratio of nautical miles (1,852 meters) to statute miles (1,609.344 meters).

Q3: Where are knots commonly used?
