Convert Electron radius (classical) to Planck length
Please provide values below to convert Electron radius (classical) [r_e] to Planck length [l_P], or Convert Planck length to Electron radius (classical).
1 r_e = 1.7435e+20 l_P. To convert Electron radius (classical) to Planck length, multiply the value by 1.7435e+20; to go the other way, divide by it (1 l_P = 5.7356e-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.
Planck Length
The Planck length is the smallest possible unit of length in the universe, approximately 1.6 x 10⁻³⁵ meters.
History/Origin
The Planck length is derived from fundamental physical constants and is named after the physicist Max Planck. It is a fundamental unit in the system of Planck units.
Current Use
The Planck length is a theoretical concept used in quantum gravity and cosmology to describe phenomena at the smallest scales of the universe.
