What are Hour and Second

Definition of Hour

An hour is a unit of time conventionally reckoned as 1⁄24 of a day and scientifically reckoned as 3,599–3,601 seconds, depending on conditions. It represents a division of the day into 24 equal parts and is used across various cultures for daily timekeeping.

Definition of Second

A second, the base unit of time in the International System of Units (SI), is defined as exactly 9,192,631,770 cycles of the radiation that corresponds to the transition between two energy levels of the cesium-133 atom. It is a consistent unit used for timekeeping globally.

Conversion of Hour to Second

1 h = 3,600 s (sidereal)
1 s (sidereal) = 1/3,600 h

Example 1:
convert 2 h to s (sidereal):
2 h = 2 × 3,600 s = 7,200 s

Example 2:
convert 5 h to s (sidereal):
5 h = 5 × 3,600 s = 18,000 s

History of Hour and Second

The concept of converting hours to sidereal seconds dates back to the necessity to align timekeeping with the stars. Ancient astronomers observed the stars for time reference, which led to the development of sidereal time, a time scale based on Earth's rotation relative to distant celestial objects.
