How to Convert Petameter to Earth's Polar Radius

1 Pm = 157313035.463093 R_p

Example: convert 15 Pm to R_p:
15 Pm = 15 Γ— 157313035.463093 R_p = 2359695531.9464 R_p


Petameter to Earth's Polar Radius Conversion Table

petameter Earth's polar radius

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.


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.
