Convert Earth's polar radius to petameter
Please provide values below to convert Earth's polar radius [R_p] to petameter [Pm], or Convert petameter to Earth's polar radius.
1 R_p = 6.3567523e-09 Pm. To convert Earth's polar radius to petameter, multiply the value by 6.3567523e-09; to go the other way, divide by it (1 Pm = 157313035.463 R_p). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

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.
Petameter
A petameter is a unit of length in the metric system equal to 10^15 meters.
History/Origin
The prefix "peta-" for 10^15 was adopted by the CGPM (General Conference on Weights and Measures) in 1975.
Current Use
The petameter is used for measuring distances on a galactic scale, such as the size of the Milky Way galaxy.
