A minute is a Unit of Time equal to 1/60th of an Hour and to 60 Second s. (Some rare minutes have 59 or 61 seconds; see Leap Second .) The minute is not a SI unit, however it is accepted for use with SI units. The correct Abbreviation for minute or minutes is "min". In Geometry , a minute is 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 . In Astronomy , the minute is 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. The symbol for a minute of arc is a Prime (′). For example, fifteen minutes could be written 15′. However, more commonly an apostrophe, or single quote ( U+0027), is used. The Earth turns on its Polar Axis through fifteen minutes of arc in every minute of time. A minute of arc at the Earth's Equator is approximately a Nautical Mile . The fact that an hour contains 60 minutes is probably due to influences from the Babylon ians, who used a Base-60 counting system. ORIGIN The first division was originally known as a "prime minute", from Latin "''(pars) minuta prima''", meaning "first minute (i.e. small) part (or division)". Likewise, the Second was known as a "second minute", meaning "the second division". SEE ALSO REFERENCES
