Second / Day Units Definition
Second
The second is a unit of measurement of time, with symbol “s” (without abbreviation). It is the sixtieth part of the minute, the minute itself being the sixtieth part of the hour. This animation represents a lightning bolt that occurs once per second.
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.
