Convert Earth's equatorial radius to foot (US survey)
Please provide values below to convert Earth's equatorial radius [R_e] to foot (US survey) [ft (US)], or Convert foot (US survey) to Earth's equatorial radius.
1 R_e = 20925604.4743 ft (US). To convert Earth's equatorial radius to foot (US survey), multiply the value by 20925604.4743; to go the other way, divide by it (1 ft (US) = 4.77883447157e-08 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.
Foot (Us Survey)
The U.S. survey foot was a unit of length defined as exactly 1200/3937 meters.
History/Origin
The U.S. survey foot was used for land surveying in the United States for most of the 20th century. Its use was officially phased out in 2022 to standardize with the international foot.
Current Use
The U.S. survey foot is now an obsolete unit.
