Convert mile (US survey) to Earth's polar radius
Please provide values below to convert mile (US survey) [mi (survey)] to Earth's polar radius [R_p], or Convert Earth's polar radius to mile (US survey).
1 mi (survey) = 0.000253171296087 R_p. To convert mile (US survey) to Earth's polar radius, multiply the value by 0.000253171296087; to go the other way, divide by it (1 R_p = 3949.8948556 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 Polar Radius
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.
