Convert rod (US survey) to Earth's equatorial radius
Enter a value below to convert rod (US survey) [rd (US)] to Earth's equatorial radius [R_e]. Reverse conversion: Convert Earth's equatorial radius to rod (US survey).
1 rd (US) = 7.88507687809e-07 R_e. To convert rod (US survey) to Earth's equatorial radius, multiply the value by 7.88507687809e-07; to go the other way, divide by it (1 R_e = 1268218.45298 rd (US)). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Rod (Us Survey): Definition and Use
A U.S. survey rod is a unit of length equal to 16.5 U.S. survey feet.
History/Origin
The U.S. survey rod 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 rod was used for land surveying in the United States.
Earth's Equatorial Radius: Definition and Use
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.
