# Minute

A minute is a customary unit of time. It is equal to 60 seconds. There are 60 minutes in an hour. Unlike the second, the minute is not an SI unit.

A minute is also ​160 of a degree. In this context, a minute is also called an arcminute, and is written with the ${\displaystyle '}$ symbol.[1][2]

For example, the Sun and Moon both have angular diameters of about 30 arcminutes—when seen from Earth.[3]
