Mile (Us Survey)
The U.S. survey mile is a unit of length equal to 5,280 U.S. survey feet.
History/Origin
The U.S. survey foot was defined such that 1 meter is exactly 39.37 inches. This made the U.S. survey mile slightly longer than the international mile. The use of the survey foot was officially phased out in 2022.
Current Use
The U.S. survey mile was used for land surveying in the United States.
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.
