The neutron has no measurable electric charge. Mass of One Neutron The mass of a free neutron is 1.6749286 x 10⁻²⁷ kg or 939,565,346 eV/c ² . In common particle physics, units of mass and energy are interchangeable. Thus, there exists at least one neutrino mass eigenstate with a mass of at least 0.05 eV. In 2009, lensing data of a galaxy cluster were analyzed to predict a neutrino mass of about 1.5 eV. This surprisingly high value requires that the three neutrino masses be nearly equal, with neutrino oscillations on the order of milli-electron-volts.
