Webb4 juli 2016 · You can guess that an electron should be big enough so that the energy in the electric field is equivalent to the rest mass of the electron (0.511 MeV). If the electron was some sort of charged jell, this would be the size of an pile of charged jell that had the rest energy of an electron. What size is that? Converting a 0.511 MeV to a distance WebbNanometers are one-billionth the size of a meter. In the past the unit was referred to as millimicrometer, or millimicron for short.
