- Homework Statement
- Silly question I know…but…the energy mass relationship is E=mc^2 with E in units of Joules. Which means mass = E/c^2 and if we take c = 1, mass = joules. So where did the conversion factor of e go when we state particle mass in eV?

- Relevant Equations
- E=mc^2

not technically a homework question, just figured it fit here.
