Naut mi is a term used in marine navigation to denote a distance of one minute of latitude, which is approximately equivalent to one nautical mile. However, there are several other terms that can be used to refer to the same distance. One such term is "arcminute", which is commonly used in astronomy and geography. Another synonym is "sea mile", which is often used interchangeably with nautical mile. Some other terms that are sometimes used to describe this distance include "knot", "cable", and "league". Regardless of the term used, a naut mi is a useful tool for measuring distances at sea and navigating through unfamiliar waters.
