Classical electron radius is calculated based on the electric charge , mass of the electron, speed of light and permittivity of free space. It is expressed as re. It is also known as Lorentz radius or Thomspon Scattering length. The value of re is 2.817 940 3267[27] e-15 m and in cgs units it is equivalant to 2.817 940 3267 (27) x 10 ^-13 cm.
