Please provide values below to convert Earth's equatorial radius [R_e] to picometer [pM], or Convert picometer to Earth's equatorial radius.
How to Convert Earth's Equatorial Radius to Picometer
1 R_e = 6.378137e+18 pM
Example: convert 15 R_e to pM:
15 R_e = 15 × 6.378137e+18 pM = 9.5672055e+19 pM

Earth's Equatorial Radius
The Earth's equatorial radius is the distance from the center of the Earth to the equator, approximately 6,378.1 kilometers.
History/Origin
The size and shape of the Earth have been a subject of study since ancient times. Modern measurements are made using satellite geodesy.
Current Use
The Earth's equatorial radius is a fundamental parameter in geodesy, geophysics, and astronomy. It is used in cartography and for defining the shape of the Earth.
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.
