Hours (hr) Conversion
An hour is a standard unit of time which is considered to be 1/24 of a day, 60 minutes and 3600 seconds.
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.
