COMMENTS
A widely-used unit of mass in particle physics.
Since 1 eV/c^2 is too small, MeV/c^2 and GeV/c^2 are more common.
Period 395732340201618.

EXAMPLE
1 eV/c^2 = (1.602176634 * 10^(-19))/299792458^2 kg = 1.7826619... * 10^(-36) kg, an order of magnitude larger than the total mass of the three neutrinos;
1 MeV/c^2 = 1.7826619... * 10^(-30) kg, about 1.96 times of the mass of an electron;
1 GeV/c^2 = 1.7826619... * 10^(-27) kg, about 1.07 times of the mass of a proton.
