How many K are in a nautical mile?
How many Kilometers equal one Nautical Mile? Exactly 1.852 kilometers equal one nautical mile, which could be written as 1.852 km = 1M using the standardized international symbols, or 1.852 km = 1 nm (or nmi) using other commonly employed symbol conventions.
How do you calculate 1 nautical mile?
A nautical mile is based on the circumference of planet Earth. If you were to cut the Earth in half at the equator, you could pick up one of the halves and look at the equator as a circle. You then divide that circle into 360 degrees, and a degree into 60 minutes. A minute of arc on planet Earth is 1 nautical mile.
How many kilometers are in a NM?

Why is there nautical miles?
(Its length has varied considerably at different periods and in different localities; the legal mile is now 1,760 yards, or 5,280 feet.) Such a linear measurement cannot be used at sea, so the nautical mile is based on the length of one minute of arc (or 1/60 of a degree) of a great circle of Earth.
Why is speed called knots?
The term knot dates from the 17th Century, when sailors measured the speed of their ship by the use of a device called a “common log.” This device was a coil of rope with uniformly spaced knots tied in it, attached to a piece of wood shaped like a slice of pie.
