Conversion constant from mass to energy

I was told at school that if we want to calculate the rest energy of the proton, we multiply its rest mass = 938 MeVc^-2 by a factor of 1.6*10^-13. However, doesn't this convert MeV to Joules only? What about the c^2? Please explain why we can omit it in our calculations. Thank you!

c2 is built into the constant you use.
