• a unit of time equal to 1/60th of an hour and to 60 seconds. (Some rare minutes have 59 or 61 seconds; see leap second.)
• a unit of time approximately equal to 1/1600th of a day, or 54 seconds (more accurately, 53.9121 seconds). Known as the natural minute to differentiate it from conventional minutes. It is equal to 10⁴⁵ Planck times.
• a unit of angle, 1/60th of a degree. It is then also known as a minute of angle or minute of arc, and can further be divided into 60 seconds of arc.
• a unit of angle and time, 1/60th of an hour of right ascension. It is then known as the minute of right ascension, and can be further divided into 60 seconds of right ascension.

The symbol for a minute of time (or of right ascension) is min.
