Inch (Us Survey)
The U.S. survey inch is a unit of length equal to 1/12 of a U.S. survey foot.
History/Origin
The U.S. survey inch is based on the U.S. survey foot, which was defined such that 1 meter is exactly 39.37 inches. The use of survey units was officially phased out in 2022.
Current Use
The U.S. survey inch was used for land surveying in the United States.
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.
