Fathom (Us Survey)
A U.S. survey fathom is a unit of length equal to 6 U.S. survey feet.
History/Origin
The U.S. survey fathom 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
The U.S. survey fathom was used in surveying in the United States.
Astronomical Unit
The astronomical unit is a unit of length, now defined as exactly 149,597,870,700 meters. It is approximately the average distance between the Earth and the Sun.
History/Origin
Historically, the astronomical unit was the mean Earth-Sun distance. In 2012, the International Astronomical Union (IAU) redefined it as a fixed constant.
Current Use
The astronomical unit is used primarily for measuring distances within the Solar System or around other stars.
