Visual comparison of a kilometre, statute mile, and nautical mile

A nautical mile is a unit of measurement used in both air and marine navigation,[2] and for the definition of territorial waters.[3] Historically, it was defined as one minute (1/60 of a degree) of latitude. Today the international nautical mile is defined as exactly 1852 metres. This converts to about 1.15 imperial/US miles. The derived unit of speed is the knot, one nautical mile per hour.

Unit symbol

There is no single internationally agreed symbol.[1]

While using M itself, the International Bureau of Weights and Measures recognises that NM, Nm and nmi are also in use.[1]
