About these units
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.
Handbreadth (handbreadth)
The handbreadth, roughly 0.1 meter, represents the width of a human hand with fingers extended. It served as a convenient, body-based subunit for cubits and larger measures. Handbreadths were integral to construction, tailoring, and craftwork, allowing precise division of larger units into manageable increments. In ancient Egyptian, Greek, and Hebrew measurement systems, the handbreadth facilitated scaling and proportioning for artisans and builders. Today, the handbreadth is mainly of historical interest, helping reconstruct ancient architectural plans and understand the human-centered logic of early measurement systems.
