Convert kiloparsec to astronomical unit
Enter a value below to convert kiloparsec [kpc] to astronomical unit [AU, UA]. Reverse conversion: Convert astronomical unit to kiloparsec.
1 kpc = 206264806.233 AU, UA. To convert kiloparsec to astronomical unit, multiply the value by 206264806.233; to go the other way, divide by it (1 AU, UA = 4.84813681143e-09 kpc). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Kiloparsec: Definition and Use
A kiloparsec is a unit of distance used in astronomy, equal to one thousand parsecs.
History/Origin
The parsec was first proposed as a unit of distance in 1913 by British astronomer Herbert Hall Turner. The kiloparsec is a multiple of the parsec used for larger astronomical distances.
Current Use
The kiloparsec is used to measure distances to objects within and around the Milky Way galaxy.
Astronomical Unit: Definition and Use
The astronomical unit is a unit of length, now defined as exactly 149,597,870,700 meters. It is approximately the average distance between the Earth and the Sun.
History/Origin
Historically, the astronomical unit was the mean Earth-Sun distance. In 2012, the International Astronomical Union (IAU) redefined it as a fixed constant.
Current Use
The astronomical unit is used primarily for measuring distances within the Solar System or around other stars.
