Please provide values below to convert Earth's distance from sun [AU_dist] to parsec [pc], or Convert parsec to Earth's distance from sun.
How to Convert Earth's Distance From Sun to Parsec
1 AU_dist = 4.84813681142745e-06 pc
Example: convert 15 AU_dist to pc:
15 AU_dist = 15 × 4.84813681142745e-06 pc = 7.27220521714118e-05 pc

Earth's Distance From Sun
The Earth's distance from the Sun varies throughout the year. The average distance is defined as one astronomical unit (AU), which is about 149.6 million kilometers.
History/Origin
The measurement of the Earth-Sun distance has a long history, with early estimates made by ancient Greek astronomers. Modern measurements are highly precise.
Current Use
The Earth-Sun distance is a fundamental unit in astronomy and is used to measure distances within the solar system.
Parsec
A parsec is a unit of length used to measure the large distances to astronomical objects outside the Solar System, approximately equal to 3.26 light-years. It is the distance at which one astronomical unit subtends an angle of one arcsecond.
History/Origin
The term "parsec" is a portmanteau of "parallax" and "second," coined by British astronomer Herbert Hall Turner in 1913.
Current Use
The parsec is the preferred unit of distance in astronomy and astrophysics for expressing the distances to stars and galaxies.
