About Week
One week is 7 days or 604,800 seconds. Weeks are used for schedules, payroll periods, and agile sprints.
About Day
One day is 24 hours or 86,400 seconds (civil day, no leap-second adjustment in this tool).
How to convert weeks to days
1 week is equal to 7 day:
1 wk = (604800 s ÷ 86400 s) d = 7 d
1 week = 7 days exactly.
Each week is defined as 604800 s and each day as 86400 s, so one wk equals 604800 ÷ 86400 d = 7 d.
Let t(wk) be the numeric value of the same duration measured in Week (wk), and t(d) the value in Day (d). Then:
t(d) = t(wk) × (604800 / 86400)
Equivalently, divide by how many wk fit into one d (seconds per d divided by seconds per wk):
t(d) = t(wk) ÷ 0.14285714285714
Or: day = week ÷ 0.14285714285714
Examples
Example #1: Convert 20 wk to day
20 wk = 20 wk × (604800/86400) d = 140 d
20 wk = 20 wk ÷ 0.14285714285714 = 140 d
Example #2: Convert 50 wk to day
50 wk = 50 wk × (604800/86400) d = 350 d
50 wk = 50 wk ÷ 0.14285714285714 = 350 d
Summary
To convert Week to Day, multiply the value in wk by the ratio of seconds per wk divided by seconds per d. Equivalently: value_d = value_wk × (604800 / 86400). Numerically, 1 wk equals 7 d.
Relationship context
Both units fall in longer spans (days to years, with average month/year definitions). Conversions use fixed second counts per unit, so factors stay consistent for estimation and UI math. The factor from Week to Day is 7.000000e+0 (1 wk = 7 d).
