Convert hours to seconds
Hour
An hour (symbol: h ; also abbreviated hr ) 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. 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.
Second
The second (symbol: s , abbreviation: sec ) is the base unit of time in the International System of Units (SI) (French: Système International d’unités), commonly understood and historically defined as 1/86400 of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each. Analogue clocks and watches often have sixty tick marks on their faces, representing seconds (and minutes), and a "second hand" to mark the passage of time in seconds. Digital clocks and watches often have a two-digit seconds counter. The second is also part of several other units of measurement like metres per second for velocity, metres per second per second for acceleration, and cycles per second for frequency.
