Convert Electron radius (classical) to ell
Please provide values below to convert Electron radius (classical) [r_e] to ell [ell], or Convert ell to Electron radius (classical).
1 r_e = 2.4654e-15 ell. To convert Electron radius (classical) to ell, multiply the value by 2.4654e-15; to go the other way, divide by it (1 ell = 4.0562e+14 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
- 1 r_e = 2.4654e-15 ell
- 1 ell = 4.0562e+14 r_e
- 10 r_e = 2.4654e-14 ell
- 100 r_e = 2.4654e-13 ell
How to Convert Electron Radius (Classical) to Ell
1 r_e = 2.46538961172353e-15 ell

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.
Ell
The ell is an obsolete unit of length, originally used for measuring cloth. Its length varied in different countries, but it was generally around 45 inches.
History/Origin
The word "ell" is derived from the Latin "ulna," meaning "forearm," as the unit was originally based on the length of the forearm.
Current Use
The ell is no longer in use.
