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.
Terameter (Tm)
A terameter equals one trillion meters (10¹² m) and is used when discussing distances that exceed the scale of the solar system but do not yet reach the interstellar unit category. Large-scale solar system phenomena—such as the size of the heliosphere, the influence boundary of the Sun's magnetic field, or trajectories of far-reaching spacecraft—may be expressed in terameters. While not widely used in astronomical literature (which often prefers astronomical units, light-years, or parsecs), the terameter provides a SI-based unit that aligns cleanly with metric prefixes. It is especially useful in theoretical physics or cosmological modeling where sticking to SI units simplifies equations.
