How to convert weeks to seconds

Multiply the value in wk by 604,800: the result is in s.

s = wk × 604,800The other way round, 1 s = 0.000001653439 wk.

Where these two units are used

The week is the only common time unit with no astronomical basis at all: neither the Sun nor the Moon yields seven days, which come from a religious usage that became universal. The second is no longer measured against the sky but against the atom: since 1967 it has been 9,192,631,770 oscillations of caesium 133, which makes it the best realised base unit of the international system. 604,800 is the number a system administrator recognises without working it out: a week in seconds, written as such in cache lifetimes and DNS zones, where the calendar does not apply.
