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

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.
