Seconds (s) Conversion

A second is an SI base unit of time which is also a fundamental unit of time for all measuring systems. It was defined as 1/86400 of a solar day, which turned out to be not accurate because the solar day is not a constant. There is another intuitive understanding that a second is about the period between beats of a human heart.
