How to Convert Week to Hour (Sidereal)
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) = 168.4599706 Hour (Sidereal) (h (Sid)).

About Week (wk)
Definition
The week is a unit of time equal to 7 days, or 604,800 seconds.
Mathematical Relationship
1 wk = 7 d = 168 h = 10,080 min = 604,800 s. A year has about 52.18 weeks.
Conversion Formula
To convert weeks to days: multiply by 7. To convert weeks to hours: multiply by 168.
Practical Applications
Pay periods (biweekly), pregnancy tracking (40 weeks), sprint cycles in agile development, and workout schedules.
Interesting Facts
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.
Common Mistakes
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.
Educational Tips
Days of the week in many languages reflect the seven celestial bodies: Sun-day, Moon-day, Saturn-day, etc.
About Hour (Sidereal) (h (Sid))
Definition
The sidereal hour is 1/24 of a sidereal day — approximately 3,590.17 seconds (59 minutes and 50.17 seconds in solar time).
Mathematical Relationship
1 sidereal hour = 3,590.17 solar seconds ≈ 59 min 50.17 s in solar time. 24 sidereal hours = 1 sidereal day.
Conversion Formula
To convert sidereal hours to solar seconds: multiply by 3,590.17. To solar hours: multiply by 0.99727.
Practical Applications
Right ascension in celestial coordinates is measured in hours (0–24 h of sidereal time), directly using sidereal hours.
Interesting Facts
Right ascension is measured in hours: 1 h of RA = 15° of sky. The entire sky is 24 sidereal hours in rotation.
Common Mistakes
Treating sidereal hours as exactly 60 solar minutes. The ~10-second difference matters for precision tracking.
Educational Tips
If you use a star-tracking telescope, it rotates once per sidereal day (23h 56m). Each sidereal hour, it covers 15° of sky.
