Convert a.u. of length to Electron radius (classical)

Please provide values below to convert a.u. of length [a.u., b] to Electron radius (classical) [r_e], or Convert Electron radius (classical) to a.u. of length.

1 a.u., b = 18778.8663968 r_e. To convert a.u. of length to Electron radius (classical), multiply the value by 18778.8663968; to go the other way, divide by it (1 r_e = 5.32513506868e-05 a.u., b). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

A.u. Of Length

The atomic unit of length, also known as the Bohr radius (a₀), is approximately 5.29 x 10⁻¹¹ meters.

History/Origin

The Bohr radius is named after Niels Bohr, who proposed a model of the atom in 1913 where the electron orbits the nucleus at specific distances. The Bohr radius is the most probable distance between the proton and electron in a hydrogen atom in its ground state.

Current Use

The atomic unit of length is used in atomic physics to simplify calculations and equations.


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.
