Rod (Us Survey)
A U.S. survey rod is a unit of length equal to 16.5 U.S. survey feet.
History/Origin
The U.S. survey rod is based on the U.S. survey foot, which was slightly different from the international foot. The use of survey units was officially phased out in 2022.
Current Use

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.
