How does this calculator work?
To convert hours to weeks divide by 168 (7 days × 24 h). Full weeks = ⌊hours ÷ 168⌋; remaining hours = hours mod 168. 168 h = 1 week; 336 h = 2 weeks; 504 h = 3 weeks. Decimal inputs (e.g. 100.5 h) are fully supported.
Formula
How this is calculated
A week contains exactly 7 days, and each day contains exactly 24 hours, so one week = 7 × 24 = 168 hours. Dividing any number of hours by 168 gives the total weeks as a decimal. For example, 200 hours ÷ 168 ≈ 1.190 weeks.
To find the full (whole) weeks and the leftover, use integer division: full weeks = floor(hours ÷ 168), and the remaining hours = hours − (full weeks × 168). Those leftover hours can further be split into whole days (÷ 24) and residual hours, so the output shows the full breakdown — e.g. 200 hours = 1 week, 1 day and 8 hours.
Longer conversions (months and years) use the standard Gregorian averages: 1 month = 365.25 ÷ 12 × 24 = 730.5 hours; 1 year = 365.25 × 24 = 8,766 hours. These are approximations because real months (28–31 days) and years (365 or 366 days) vary. All hours-to-weeks conversions are exact.
Frequently asked questions
Exactly 168 hours — 7 days × 24 hours per day = 168 hours. This is the basis for all the conversions on this page.
336 ÷ 168 = exactly 2 weeks. Any multiple of 168 converts cleanly to a whole number of weeks.
1,000 ÷ 168 ≈ 5.952 weeks, which is 5 full weeks, 6 days and 16 hours. Divide the remainder hours by 24 to get the days and residual hours.
