Minute (min)
The minute, symbol min, is 60 seconds. Its name comes from the Latin for “first small part.” Minutes have been used since ancient times when base-60 number systems shaped early timekeeping. Minutes are part of daily life—used in clocks, plans, and math. Although the SI system uses seconds, minutes are still important for daily and cultural needs, thereby linking science with everyday life.
