Convert Electron radius (classical) to astronomical unit
Please provide values below to convert Electron radius (classical) [r_e] to astronomical unit [AU, UA], or Convert astronomical unit to Electron radius (classical).
1 r_e = 1.8837e-26 AU, UA. To convert Electron radius (classical) to astronomical unit, multiply the value by 1.8837e-26; to go the other way, divide by it (1 AU, UA = 5.3088e+25 r_e). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference

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.
Astronomical Unit
The astronomical unit is a unit of length, now defined as exactly 149,597,870,700 meters. It is approximately the average distance between the Earth and the Sun.
History/Origin
Historically, the astronomical unit was the mean Earth-Sun distance. In 2012, the International Astronomical Union (IAU) redefined it as a fixed constant.
Current Use
The astronomical unit is used primarily for measuring distances within the Solar System or around other stars.
