Hours
An hour is a unit of time equal to 60 minutes or 3,600 seconds. It’s commonly used to divide the day into manageable portions, helping us structure our daily activities, work schedules, and leisure time. Hours are a fundamental part of timekeeping, found in everything from clocks on the wall to the timing systems of modern technology.
Seconds
The second is the fundamental unit of time, often considered the building block of more extended periods. It is defined as the time it takes for a specific number of vibrations of a cesium atom (9,192,631,770 to be precise). Seconds are crucial in everyday life, used to measure short durations and split more extended periods into manageable parts. From tracking the time during a race to counting down for a rocket launch, the second is essential in both everyday and scientific contexts.
