To convert weeks to days: multiply by 7. To convert weeks to hours: multiply by 168.
1 wk = 7 d = 168 h = 10,080 min = 604,800 s. A year has about 52.18 weeks.
For example, 1 Week (wk) = 168 Hour (h).
| Week (wk) | Hour (h) |
|---|---|
| 0.1 | 16.8 |
| 0.5 | 84 |
| 1 | 168 |
| 2 | 336 |
| 5 | 840 |
| 10 | 1680 |
| 25 | 4200 |
| 50 | 8400 |
| 100 | 16800 |
| 500 | 84000 |
| 1000 | 168000 |
The week is a unit of time equal to 7 days, or 604,800 seconds.
1 wk = 7 d = 168 h = 10,080 min = 604,800 s. A year has about 52.18 weeks.
To convert weeks to days: multiply by 7. To convert weeks to hours: multiply by 168.
Pay periods (biweekly), pregnancy tracking (40 weeks), sprint cycles in agile development, and workout schedules.
The seven-day week has no astronomical basis — unlike days, months, and years, it's a purely human invention. It has been continuous for thousands of years.
Assuming months are exactly 4 weeks — most months are 4.3 weeks (30–31 days). Only February in non-leap years is exactly 4 weeks.
Days of the week in many languages reflect the seven celestial bodies: Sun-day, Moon-day, Saturn-day, etc.
The hour is a unit of time equal to 60 minutes, or 3,600 seconds.
1 h = 60 min = 3,600 s = 3.6 × 10⁶ ms. There are 24 hours in a day and 8,760 in a non-leap year.
To convert hours to minutes: multiply by 60. To convert hours to seconds: multiply by 3,600.
Work schedules, flight durations, speed limits (km/h, mph), cooking times, and pay rates (hourly wages).
Before mechanical clocks, 'hours' varied by season — a summer daytime hour was longer than a winter one. These were called 'temporal hours.'
Converting decimal hours to minutes/seconds incorrectly: 2.5 h = 2 h 30 min, not 2 h 50 min. Think base-60.
The kilowatt-hour (kWh) on your electric bill is energy = power × time. 1 kWh = using 1,000 watts for 1 hour.
