Please provide values below to convert picometer [pM] to Earth's polar radius [R_p], or Convert Earth's polar radius to picometer.
How to Convert Picometer to Earth's Polar Radius
1 pM = 1.57313035463093e-19 R_p
Example: convert 15 pM to R_p:
15 pM = 15 × 1.57313035463093e-19 R_p = 2.3596955319464e-18 R_p
Picometer to Earth's Polar Radius Conversion Table

Picometer
A picometer is a unit of length in the metric system equal to 10^-12 meters.
History/Origin
The prefix "pico-" for 10^-12 was adopted by the CGPM (General Conference on Weights and Measures) in 1960.
Current Use
The picometer is used to measure atomic and subatomic particle dimensions.
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.
