Please provide values below to convert Electron radius (classical) [r_e] to Earth's equatorial radius [R_e], or Convert Earth's equatorial radius to Electron radius (classical).
How to Convert Electron Radius (Classical) to Earth's Equatorial Radius
1 r_e = 4.41812448713472e-22 R_e
Example: convert 15 r_e to R_e:
15 r_e = 15 × 4.41812448713472e-22 R_e = 6.62718673070208e-21 R_e

Electron Radius (Classical)
The classical electron radius is a quantity with the dimension of length, approximately 2.82 x 10⁻¹⁵ meters.
History/Origin
The classical electron radius is a concept from classical physics that attempts to model the electron as a spherical shell of charge. It is not considered the actual size of an electron.
Current Use
The classical electron radius appears in the Thomson scattering cross-section and is a useful length scale in atomic and high-energy physics.
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.
