Electron Radius (re)
The classical electron radius, approximately 2.818 × 10⁻¹⁵ meters, is a theoretical value derived from classical electromagnetic theory rather than an actual measured size. It represents the radius a charged sphere would need to have in order for its electrostatic self-energy to equal the electron's rest energy. Although electrons are now understood to be point-like or extremely small compared to this radius, the classical electron radius remains useful in scattering theory, especially in calculations involving Thomson scattering — the elastic scattering of electromagnetic radiation by free electrons. Thus, while not a physical dimension of the electron, the classical radius serves as a meaningful parameter in specific areas of physics and retains importance in radiation modeling and plasma physics.
Kiloyard (kyd)
The kiloyard is equal to 1,000 yards (914.4 meters), providing a metric-like large-scale measure within the imperial system. It is occasionally used in sports, military, or surveying contexts where distances are large but must be expressed in imperial units. While uncommon in everyday practice, the kiloyard simplifies arithmetic over vast distances, especially when dealing with thousands of yards rather than dealing with long numbers of individual yards. Its usage demonstrates the adaptability of traditional systems to meet the need for larger-scale measurements without switching fully to metric units.
