Second is the System International (SI) base unit to measure the time duration. In other words, it is also defined as 86,400th part of a one day. The calculation can be easily obtained if we evaluate total number of seconds in a day. The rational definition of second includes time difference between heart beats or a pulse rate.
Importance: It is base unit and all the others are derived from this unit and their standard prefixes are also extracted from this unit.
Symbol and Unit: It is SI base unit of time and its symbol is 's' or sometimes 'sec'.

An hour is a unit of time which represents 1 by 24th part of the day. Duration of 60 minutes or 3600 seconds is termed as 1 hour.
Importance: Since, in one day there are 24 hours and 12 hour clock is used to represent these hours. AM (ante meridiem) and PM (post meridiem) are also used with these hours to indicate the timing of morning, afternoon and evening. The timings of dusk, dawn and midnight are intended by using 12 hour clock.
