km to Nautical Miles Converter
Convert land kilometers to nautical miles. Professional maritime and aviation tool with scientific precision for navigation charts and travel logs.
About
In the domains of maritime shipping and international aviation, distance is measured not in statute kilometers but in nautical miles. This unit is based on the circumference of the Earth and corresponds to one minute of latitude. Mixing these units can lead to navigational hazards, fuel miscalculations, or violations of international transport protocols.
This tool is engineered for sailors, pilots, and logistics coordinators. It strictly adheres to the international definition where one nautical mile equals exactly 1,852 meters. The interface distinguishes clearly between the input "land" units and output "air/sea" units, preventing the common confusion between the statute mile and the nautical mile.
Formulas
The nautical mile is defined exactly as 1,852 meters. To convert kilometers to nautical miles, we divide the kilometer value by 1.852.
