Foot (Us Survey)
The U.S. survey foot was a unit of length defined as exactly 1200/3937 meters.
History/Origin
The U.S. survey foot was used for land surveying in the United States for most of the 20th century. Its use was officially phased out in 2022 to standardize with the international foot.
Current Use
The U.S. survey foot is now an obsolete unit.
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.
