Fathom (Us Survey): Definition and Use
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 Polar Radius: Definition and Use
The Earth's polar radius is the distance from the center of the Earth to the North or South Pole, approximately 6,356.8 kilometers.
History/Origin
The fact that the Earth is an oblate spheroid, flattened at the poles, has been known since the 18th century. Modern measurements are made with high precision.
Current Use
The Earth's polar radius is a key parameter in geodesy and is used to define the Earth's shape and gravitational field.
