Note
This is a simplified model: it applies a standard navigation, performance or seamanship formula to the numbers you entered. True airspeed and density altitude use the ISA troposphere model for dry air and ignore humidity, compressibility and instrument or position error, so they are not a substitute for your aircraft's flight manual or an air data computer. Wind, climb, descent and fuel figures assume a steady wind and a constant speed and fuel flow for the whole leg; they ignore manoeuvring, holding, taxi and start-up fuel, terrain, turbulence and air traffic control routing. Takeoff distance scales an entered sea level figure by a rule-of-thumb percentage per 1000 ft of density altitude and is not a certified performance chart. Weight and balance results depend entirely on the arms and weights you enter and must be checked against the approved loading envelope. Hull speed is the classic 1.34 × √LWL displacement estimate, boat fuel burn is a horsepower-based approximation, anchor scope is a rule of thumb, and the rule of twelfths is a linear approximation of a sinusoidal tide that does not hold in all locations. Always use official charts, tide tables, the aircraft or vessel manuals and current weather, and treat these numbers as planning estimates only.

What is a nautical mile and why is it different from a statute mile or kilometer?+
A nautical mile is defined as one minute of arc of latitude along a meridian, equal to exactly 1,852 meters. It's used in aviation and maritime navigation because it relates directly to the geometry of the globe, unlike the statute mile or metric units, which don't align as neatly with charts and coordinates.
What is the exact conversion factor used here?+
1 nautical mile equals exactly 1.852 kilometers (or 1,852 meters). This is an internationally defined exact value, not an approximation, so the conversion is a simple multiplication with no rounding error introduced by the constant itself.
Why do pilots and sailors still use nautical miles instead of kilometers?+
Charts, GPS displays, and navigation instruments in aviation and maritime contexts are built around nautical miles because they correspond directly to latitude on a chart, making distance and position calculations more intuitive when working with lat/long coordinates.
What's a common mistake when converting nautical miles to kilometers?+
Confusing nautical miles with statute (land) miles, which use a different conversion factor (1 statute mile = 1.609 km). Using the wrong mile definition introduces roughly a 15% error, which matters a great deal for fuel planning or ETA calculations.
Does this conversion depend on speed or is it purely a distance conversion?+
It's purely a distance conversion and doesn't involve speed or time at all. To convert a speed like knots (nautical miles per hour) to km/h, the same 1.852 factor is applied, but that is a related, separate calculation from a plain distance conversion.
