Convert Earth's equatorial radius to inch (US survey)
Please provide values below to convert Earth's equatorial radius [R_e] to inch (US survey) [in (US)], or Convert inch (US survey) to Earth's equatorial radius.
1 R_e = 251107253.691 in (US). To convert Earth's equatorial radius to inch (US survey), multiply the value by 251107253.691; to go the other way, divide by it (1 in (US) = 3.98236205964e-09 R_e). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

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.
Inch (Us Survey)
The U.S. survey inch is a unit of length equal to 1/12 of a U.S. survey foot.
History/Origin
The U.S. survey inch is based on the U.S. survey foot, which was defined such that 1 meter is exactly 39.37 inches. The use of survey units was officially phased out in 2022.
Current Use
The U.S. survey inch was used for land surveying in the United States.
