1. What is a Kts to Mph Calculator?

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

Purpose: It helps aviators, mariners, 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
• \( S_{kts} \) — Speed in knots
• 1.15078 — Conversion factor (1 knot = 1.15078 mph)

Explanation: The conversion factor comes from the ratio of nautical miles to statute miles (1.15078).

3. Importance of Speed Conversion

Details: Accurate speed conversion is crucial for flight planning, navigation, weather reporting, and when comparing speed measurements from different sources.

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: Why is the conversion factor 1.15078?
A: This factor represents the ratio of a nautical mile (1.852 km) to a statute mile (1.60934 km).

Q2: When would I need to convert knots to mph?
A: Common when interpreting aviation/marine speeds for land-based applications or public weather reports.

Q3: Is there a simple approximation I can use?
A: For quick estimates, you can multiply knots by 1.15 (about 1.5% error).

Q4: What's the difference between knots and mph?
A: Knots are nautical miles per hour (used in aviation/marine), while mph are statute miles per hour (used on land).

Q5: How accurate is this conversion?
A: The conversion factor is exact, so results are mathematically precise.
