Im trying to use the Bethe formula (http://en.wikipedia.org/wiki/Bethe_formula) to find dE/dx for a particle through a material, but I am not getting the units to work out. In the part of the formula with (e^2/4PiEpsilon)^2, how should I convert this correctly? Those units are J*m, so can I just multiply by 100 to get it to J*cm and divide by 1x10^-6 to get it into MeV*cm?
