heure

An hour (symbol: h ; aussi abbreviated hr ) est une unité de time conventionally reckoned as 1/24 of a day and scientifically reckoned as 3,599–3,601 seconds, depending on conditions. There are 60 minutes in an hour, and 24 hours in a day.

The hour was initially established in the ancient Near East as a variable measure of 1/12 of the night or daytime. Such seasonal , temporal , or unequal hours varied by season and latitude. 


seconde

La second (symbol: s , abréviation: sec ) is the unité de base de temps dans le Système international d'unités (SI) (SI) (French: Système International d’unités), couramment understood and historiquement défini comme 1/86400 of a day – ce factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each. Analog clocks and watches souvent have sixty tick marks on their faces, representing seconds (and minutes), and a "second hand" to mark the passage de temps in seconds. Digital clocks and watches souvent have a two-digit seconds counter. La seconde is aussi part of several other units of measurement like meters par seconde for velocity, meters par seconde par seconde for acceleration, and cycles par seconde for frequency.
