Convert Earth's equatorial radius to chain (US survey)

Please provide values below to convert Earth's equatorial radius [R_e] to chain (US survey) [ch (US)], or Convert chain (US survey) to Earth's equatorial radius.

1 R_e = 317054.613245 ch (US). To convert Earth's equatorial radius to chain (US survey), multiply the value by 317054.613245; to go the other way, divide by it (1 ch (US) = 3.15403075125e-06 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.


Chain (Us Survey)

A U.S. survey chain is a unit of length equal to 66 U.S. survey feet.

History/Origin

The U.S. survey chain is based on the U.S. survey foot, which was slightly different from the international foot. The use of survey units was officially phased out in 2022.

Current Use

The U.S. survey chain was used for land surveying in the United States.
