About these units
Vara Conuquera (vara conuquera)
The Vara Conuquera is another regional variant of the vara, used primarily in Chile, with a slightly different length than the standard vara. It was closely associated with land measurement, particularly in defining plots for cultivation and property boundaries in rural communities. Its use highlights the way local measurement systems adapted colonial Spanish units to meet practical needs. Land surveyors, farmers, and municipal officials relied on the Vara Conuquera for legal documentation, taxation, and irrigation planning. Today, knowledge of the Vara Conuquera is mostly of historical and legal interest, providing context for land disputes, heritage records, and the evolution of measurement in Chilean history.
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.
