Gigameter
A gigameter is a unit of length in the metric system equal to 10^9 meters.
History/Origin
The prefix "giga-" for 10^9 was adopted by the CGPM (General Conference on Weights and Measures) in 1960.
Current Use
The gigameter is used for measuring interplanetary distances, for example, the distance between Earth and Mars.
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.
