How to Convert Hour (Sidereal) to Minute
To convert sidereal hours to solar seconds: multiply by 3,590.17. To solar hours: multiply by 0.99727.
1 sidereal hour = 3,590.17 solar seconds ≈ 59 min 50.17 s in solar time. 24 sidereal hours = 1 sidereal day.
For example, 1 Hour (Sidereal) (h (Sid)) = 59.83617333 Minute (min).

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.
About Minute (min)
Definition
The minute is a unit of time equal to 60 seconds, or 1/60 of an hour.
Mathematical Relationship
1 min = 60 s = 1/60 h = 60,000 ms. There are 1,440 minutes in a day and 525,960 in a year.
Conversion Formula
To convert minutes to seconds: multiply by 60. To convert minutes to hours: divide by 60.
Practical Applications
Meeting schedules, cooking times, exercise intervals, transit timetables, and phone call durations.
Interesting Facts
The minute hand on a clock rotates 360° per hour (6° per minute). There are exactly 525,600 minutes in a non-leap year.
Common Mistakes
Using decimal hours incorrectly: 1.5 hours = 90 minutes, not 1 hour 50 minutes. The base-60 system catches people off guard.
Educational Tips
The Babylonians gave us base-60 time. That's why we have 60 seconds per minute and 60 minutes per hour — it's not decimal!
