Kilometer
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.
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.
