This time period is used for a wide range of purposes, from scheduling appointments and meetings, to measuring the duration of events and activities, to tracking the passage of time in scientific experiments and research.

An hour is one of the seven basic units of the International System of Units (SI), which is the modern version of the metric system. The symbol for hour is "h". The word "hour" comes from the Latin word "hora", which means "time of day" or "hour of the day". One hour is equal to 1/24th of a day, or one 24th of the time it takes for the Earth to complete one rotation on its axis.
