... 1 unit of charge is 1.602 x 10-19 coulombs. A proton is given a charge of +1 and an electron a charge of -1. All charges are measured in these units. 1 unit of mass is 1.661 x 10-27 kg. This is also not a convenient number, so we use “atomic mass units”. Since the mass of protons and neutrons varies ...
