Convert astronomical unit to Earth's polar radius
Please provide values below to convert astronomical unit [AU, UA] to Earth's polar radius [R_p], or Convert Earth's polar radius to astronomical unit.
1 AU, UA = 23533.6951386 R_p. To convert astronomical unit to Earth's polar radius, multiply the value by 23533.6951386; to go the other way, divide by it (1 R_p = 4.2492264564e-05 AU, UA). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Astronomical Unit
The astronomical unit is a unit of length, now defined as exactly 149,597,870,700 meters. It is approximately the average distance between the Earth and the Sun.
History/Origin
Historically, the astronomical unit was the mean Earth-Sun distance. In 2012, the International Astronomical Union (IAU) redefined it as a fixed constant.
Current Use
The astronomical unit is used primarily for measuring distances within the Solar System or around other stars.
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.
