Hour / Day Units Definition
Hour
An hour is a unit of time that divides a day into 24 equal parts. So there are 24 hours in a day. A minute is a unit of time that divides an hour into 60 equal parts. So there are 60 minutes in an hour.
Day
The day is also a unit of time which, although outside the International System (SI), is in use with it. It is worth exactly 86,400 seconds and its symbol is “d” (from the Latin dies, but also the initial of the English word day). The French abbreviation “j” is nevertheless frequently used.
