Convert parsec to Earth's equatorial radius
Please provide values below to convert parsec [pc] to Earth's equatorial radius [R_e], or Convert Earth's equatorial radius to parsec.
1 pc = 4837897933.64 R_e. To convert parsec to Earth's equatorial radius, multiply the value by 4837897933.64; to go the other way, divide by it (1 R_e = 2.0670e-10 pc). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 pc = 4837897933.64 R_e

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.
Earth's Equatorial Radius
The Earth's equatorial radius is the distance from the center of the Earth to the equator, approximately 6,378.1 kilometers.
History/Origin
The size and shape of the Earth have been a subject of study since ancient times. Modern measurements are made using satellite geodesy.
Current Use
The Earth's equatorial radius is a fundamental parameter in geodesy, geophysics, and astronomy. It is used in cartography and for defining the shape of the Earth.
