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.
Megaparsec
A megaparsec is a unit of distance used in astronomy, equal to one million parsecs.
History/Origin
The parsec was first coined by British astronomer Herbert Hall Turner in 1913. The megaparsec came into use as astronomical distance measurements extended to other galaxies.
Current Use
The megaparsec is used to measure the distances between neighboring galaxies and galaxy clusters.
