Please provide values below to convert Earth's polar radius [R_p] to furlong (US survey) [fur (US)], or Convert furlong (US survey) to Earth's polar radius.
How to Convert Earth's Polar Radius to Furlong (Us Survey)
1 R_p = 31599.158844824 fur (US)
Example: convert 15 R_p to fur (US):
15 R_p = 15 × 31599.158844824 fur (US) = 473987.38267236 fur (US)

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.
Furlong (Us Survey)
A U.S. survey furlong is a unit of length equal to one-eighth of a U.S. survey mile.
History/Origin
The U.S. survey furlong 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 furlong was used in land surveying in the United States.
