1. What is the Kilometers to Nautical Miles Conversion?

The conversion between kilometers and nautical miles is essential for marine and aviation navigation. One nautical mile equals exactly 1.852 kilometers, based on the circumference of the Earth.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( D_{nm} \) — Distance in nautical miles
• \( D_{km} \) — Distance in kilometers
• 1.852 — Conversion factor (km per nautical mile)

Explanation: The formula divides the distance in kilometers by 1.852 to get the equivalent distance in nautical miles.

3. Importance of Nautical Miles

Details: Nautical miles are used worldwide for maritime and aviation purposes because they are directly related to the Earth's latitude/longitude coordinate system (1 nautical mile = 1 minute of latitude).

4. Using the Calculator

Tips: Enter distance in kilometers (must be a positive number). The calculator will automatically compute the equivalent distance in nautical miles.
