 P: 4 Hello! I'm also confused regarding these units, given the equation E=$$\gamma$$mc2, i am to show the mass of a proton in the units MeV/C^2, however i have no idea how to convert into these units. Is this form of the display of mass actually a measure of the relativistic energy that the particle has?
