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.
Earth's Equatorial Radius
The Earth's equatorial radius is the distance from the center of the Earth to the equator, approximately 6,378.1 kilometers.
History/Origin
The size and shape of the Earth have been a subject of study since ancient times. Modern measurements are made using satellite geodesy.
Current Use
The Earth's equatorial radius is a fundamental parameter in geodesy, geophysics, and astronomy. It is used in cartography and for defining the shape of the Earth.
