Hi, I'm really struggling with converting between Joules, kg and MeV/c^2. I never know when to use c^2 in the equations.
I've worked out that to convert from MeV/c^2 to energy:
mass (MeV/c^2) x eV = energy (J)
Can anyone please tell me the similar equations for converting kg to energy and MeV/c^2 to kg?
Thanks - any help would be massively appreciated!
