Day / Century Units Definition
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.
Century
A century is a period of one hundred years. The word comes from the Latin saeculum, which meant “race”, “generation”. He then indicated the duration of a human generation and it was 33 years 4 months. Very quickly, the century designated a duration of 100 years.
