Convert Minutes to Sidereal Years
Convert Minutes (min) to Sidereal Years (a_sid) instantly and accurately.
Conversion Formula
a_sid = min × 1.901252147e-6
About Minutes
A minute (min) = exactly 60 s, inherited from Babylonian sexagesimal astronomy. Medieval astronomers named the sixtieth part of a degree 'pars minuta prima' (hence minute); its sixtieth 'pars minuta secunda' (hence second). Running performance is expressed in min/km or min/mile; music tempo in BPM (beats per minute, ~40-220); angles in degrees-minutes-seconds (DMS). 1 min = 60 s = 1/60 h.
About Sidereal Years
The sidereal year = Earth's orbital period relative to the stars = 365.25636 days = 31,558,149.8 s - about 20 min 24 s longer than the tropical year. The gap arises from precession of the equinoxes (~50 arcsec/year westward drift), which causes the tropical year to end slightly before the sidereal orbit completes. JPL DE440 ephemerides and J2000.0 epoch are anchored to the sidereal frame. 1 a_sid = 365.25636 d.
