About Weeks and Hours
Weeks (wk): Seven days, an ancient convention with no astronomical basis (unlike the day, month, and year); standardized across most cultures despite no natural cause for the seven-day cycle. Common uses: Work cycles, paychecks, school schedules, and project planning in the 1-3 month range.
Hours (hr): Sixty minutes, derived from the Egyptian division of day and night into 12 parts each; the 24-hour day is much older than the modern second. Common uses: Work schedules, sleep tracking, journey lengths, billing (hourly rates), and any time interval longer than a few minutes.
How the conversion works
Time uses fixed SI seconds. A day is exactly 86,400 seconds; a year (Julian) is 365.25 days = 31,557,600 seconds.
The exact relationship is hours = weeks × 168, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.
When this conversion matters
Converting between weeks and hours comes up wherever time measurements move between systems — from one country's conventions to another's, from a scientific reference to a practical specification, or from one industry's working unit to another's. The calculator and reference table above cover the everyday range; for unusual values you can type any number into either field.
