Convert rod (US survey) to Earth's polar radius
Please provide values below to convert rod (US survey) [rd (US)] to Earth's polar radius [R_p], or Convert Earth's polar radius to rod (US survey).
1 rd (US) = 7.91160300268e-07 R_p. To convert rod (US survey) to Earth's polar radius, multiply the value by 7.91160300268e-07; to go the other way, divide by it (1 R_p = 1263966.3538 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)
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 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.
Frequently Asked Questions
What is 1 rod (US survey) in Earth's polar radius?
1 rod (US survey) (rd (US)) = 7.91160300268e-07 Earth's polar radius (R_p).
