How to Convert Kilometers to Nautical Miles
Nautical mile is a unit for distances on sea. You use it also in shipping, trips, naval charts and speeds. The international nautical mile matches exactly 1 852 meters.
That is likewise as 1,852 kilometers. Nautical mile is a bit longer than land mile. It matches around 1,1508 statute miles.
Some say that nautical mile is 6 000 feet.
Are various ways address the calculations for convert between these units. For turn kilometers in nautical miles, you share the value by means of 1,852. For instance, 15 km matches around 8,10 nautical miles.
Otherwise you can multiply the kilometers by means of 0,5399568035. For 100 km that gives approximately 54 international nautical miles. One kilometer is around 0,54 nautical miles.
Usually you remember that nautical mile is almost twice shorter than 10 % less in kilometers so factor of 1,8.
Nautical mile bases on the length of the Earth and latitude coordinates. Historically you defined it as 60 minutes of 360 degrees. One nautical mile matches around 1,8 km.
In the Mid Atlantic maritime provisions range according to distances of coast. Typical changes happen under 20 nautical miles of the beach. More visible differences come around the 100-200-fathom-line.
Even modern yachting associations and contests use occasionally nautical miles although metric units are precise and practical. One writes one nautical mile as 1 nm either nmi. Symbols as 1,852 km = 1 nm are usual.
Conversion calculators and tables on-line help to quickly count such lengths.
