Convert mile (US survey) to Earth's equatorial radius
Please provide values below to convert mile (US survey) [mi (survey)] to Earth's equatorial radius [R_e], or Convert Earth's equatorial radius to mile (US survey).
1 mi (survey) = 0.0002523224601 R_e. To convert mile (US survey) to Earth's equatorial radius, multiply the value by 0.0002523224601; to go the other way, divide by it (1 R_e = 3963.18266556 mi (survey)). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

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.
