Unit of Time

The unit of time is second in all the systems of units.

But the multiple unit of second (for example: minute, hour. day, month, year etc.) rather than second it is used more in our real life. The time taken by the earth to rotate once round its own axis is equivalent to one day. The one twenty-four part of a day is one hour and the one sixtieth part of an hour is one minute. The one sixtieth part of a minute is our fundamental unit of time that is one second. Hence,

1 day = 24 hours

1 hour = 60 Minute

1 minute = 60 Seconds.
