Dead reckoning relies on precise distance measurements to plot a vessel’s course when external references are unavailable. In maritime navigation, distances are commonly expressed in nautical miles, which are defined by the Earth’s geometry and equal one minute of latitude.
Coastal navigation often requires converting between nautical miles, kilometres, and statute miles to integrate chart data, GPS outputs, and local regulations. Understanding the fixed conversion factors ensures consistency across different navigation tools and legal requirements.
The fundamental relationships are linear: one nautical mile equals exactly 1.852 kilometres and approximately 1.15078 statute miles. These constants allow quick mental checks and are the basis for the conversion calculator.
