Convert Earth's equatorial radius to Electron radius (classical)
Please provide values below to convert Earth's equatorial radius [R_e] to Electron radius (classical) [r_e], or Convert Electron radius (classical) to Earth's equatorial radius.
1 R_e = 2.2634e+21 r_e. To convert Earth's equatorial radius to Electron radius (classical), multiply the value by 2.2634e+21; to go the other way, divide by it (1 r_e = 4.4181e-22 R_e). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

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.
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.
