How to Convert Ell to Electron Radius (Classical)
1 ell = 405615402630381 r_e
Example: convert 15 ell to r_e:
15 ell = 15 × 405615402630381 r_e = 6.08423103945571e+15 r_e
Ell to Electron Radius (Classical) Conversion Table
| ell | Electron radius (classical) |

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.
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.
