About these units
Famn (famn)
The famn, related to the English fathom, was a Scandinavian unit roughly equal to 1.78 meters. Like other fathoms, it originated as the distance between a person's outstretched arms, making it a natural measure for tasks performed at arm's length. Historically, the famn was used in maritime contexts, forestry, and measuring firewood. Sailors relied on it when describing water depth, rope lengths, and the dimensions of boats. On land, stacked firewood was often quantified in famnar, making the unit central to resource management in cold northern regions. Today, the famn has largely disappeared from practical use, but it continues to appear in maritime literature, folklore, and historical accounts. Its surviving references help illuminate the working methods and daily experiences of Nordic sailors, fishermen, and rural communities prior to metrication.
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.
