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.
Millimeter (mm)
A millimeter is one-thousandth of a meter and is used extensively in fields that require fine control and precision. Engineers and machinists frequently rely on millimeters in technical drawings and machining specifications, since the unit supports very precise tolerances without resorting to decimals. In construction, millimeters provide clarity for component dimensions, door and window fittings, and joinery work. Millimeters are also critical in medical imaging (such as CT or MRI slice thickness), entomology, electronics, and automotive design. Many mechanical failures or malfunctions arise from deviations of only a few millimeters—highlighting the importance of precision. On a more everyday level, rainfall measurements and snow depth reports often use millimeters for accuracy.
