Famn
A famn is an obsolete Swedish unit of length, equivalent to 3 aln or about 1.78 meters.
History/Origin
The famn was the Swedish version of the fathom, based on the span of outstretched arms.
Current Use
The famn 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.
