Please provide values below to convert picometer [pM] to Earth's equatorial radius [R_e], or Convert Earth's equatorial radius to picometer.
How to Convert Picometer to Earth's Equatorial Radius
1 pM = 1.5678559428874e-19 R_e
Example: convert 15 pM to R_e:
15 pM = 15 × 1.5678559428874e-19 R_e = 2.3517839143311e-18 R_e
Picometer to Earth's Equatorial 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 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.
