minute of latitude

One minute of latitude is exactly 1/60 of a degree of angular latitude; its physical meridional arc length is not constant everywhere on an ellipsoidal Earth.

One minute of latitude is understood to be about 0.0002908882 radians.

NOAA explains the nautical mile's navigation connection through latitude and longitude; the modern international nautical mile is separately fixed at exactly 1852 m.

Modern use is context-dependent and varies by region or measurement system.
