Convert kiloparsec to kilometer
Enter a value below to convert kiloparsec [kpc] to kilometer [km]. Reverse conversion: Convert kilometer to kiloparsec.
1 kpc = 3.0857e+16 km. To convert kiloparsec to kilometer, multiply the value by 3.0857e+16; to go the other way, divide by it (1 km = 3.2408e-17 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.
Kilometer: Definition and Use
A kilometer is a unit of length in the metric system, equal to one thousand meters.
History/Origin
The term "kilometer" is derived from the Greek words "khilioi" (thousand) and "metron" (measure). The kilometer was first defined as part of the metric system in France in 1795.
Current Use
The kilometer is the most widely used unit of distance for road signs and travel distances in the world, with the notable exceptions of the United States and the United Kingdom.
