Fingerbreadth
A fingerbreadth is an ancient unit of length, based on the width of a finger, approximately 3/4 of an inch.
History/Origin
The fingerbreadth was a common unit of measurement in many ancient cultures.
Current Use
The fingerbreadth is an obsolete unit of measurement.
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.
