The formula
d = wk × 7
Worked through with a real value: 10 weeks = 70 days.
Going the other way: wk = d × 0.142857, so 1 day = 0.142857 weeks.
What each unit is
- week wk
- Seven days, the standard period for work weeks, rent and recurring schedules.
- day d
- Twenty-four hours, the time of one complete Earth rotation and the calendar base unit.
Where these come from
- 1 week = 604800 seconds
- 1 day = 86400 seconds
Every other number on this page is computed from those, and each category is pinned to conversions worked out by hand from the units' primary definitions before it ships.
