Perch
A perch is a unit of length equal to a rod, which is 16.5 feet.
History/Origin
The term "perch" has been used as a unit of measurement since medieval times and was often used interchangeably with "rod" and "pole."
Current Use
The perch 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.
