The Conversion Formula
To convert hours to seconds, multiply the value by the conversion factor: 1 h = 3600 s. For a worked example, suppose you need to convert 25 h to seconds: 25 × 3600 = 90000 s. To convert in the opposite direction, divide by 3600, or equivalently multiply by 0.000277778.
About hours
The hour was originally defined as 1/12th of the time between sunrise and sunset, meaning hours changed length with the seasons! Fixed-length hours only became standard with the invention of mechanical clocks in the 14th century.

The ISS orbits the Earth every 1.5 hours.
About seconds
The second is the fundamental unit of time in the International System of Units (SI). Originally defined as 1/86,400 of a mean solar day, it is now defined with extreme precision by the radiation frequency of the cesium-133 atom. This 'atomic time' allows GPS satellites and the internet to function synchronously. seconds are commonly used in Sports timing, Scientific experiments, Cooking timers, and Internet protocols, Heart rate measurement.
A healthy resting heart beats roughly once per second.
