* * 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. This comes from the definition of the meter as a based unit in the metric system, and the definition of the nautical mile which is relative to the meter.

* * Difference between Nautical Miles and Kilometers

Both units are used to measure significant distances of comparable magnitude, but while the kilometer is used more universally, the nautical mile is mostly used in marine navigation and sea distance measurement, as well as air navigation in aviation.

Historically, the nautical mile was defined as one minute of latitude, thus equivalent to one sixtieth of a degree. The meter, on the other hand, is a more modern measurement unit and while it has been redefined several times to ensure it stays the same no matter what, it is now defined as the distance light travels in 1/299,792,458 seconds in a vacuum.

* * How to convert Nautical Miles to Kilometers

To convert from nautical miles to kilometers, multiply the measurement in M (nm, nmi) by 1.852 to get the equivalent in km. This is done easily using a free online converter such as ours, or your handy old-school calculator or a mobile calculator app.
