Weeks to Days
A week is 7 days, a unit with no astronomical basis but used worldwide for scheduling and calendars. A day is 24 hours, based on one full rotation of the Earth on its axis. 1 wk equals 7 day, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to time, measured here against time's base unit (s) — every other time unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
day = wk × 7
wk = day × ≈0.142857
