Mile (Us Survey)
The U.S. survey mile is a unit of length equal to 5,280 U.S. survey feet.
History/Origin
The U.S. survey foot was defined such that 1 meter is exactly 39.37 inches. This made the U.S. survey mile slightly longer than the international mile. The use of the survey foot was officially phased out in 2022.
Current Use
The U.S. survey mile was used for land 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.
