Hi!
I know the mass of, for instance, an electron can be express in units of electronvolts over speed of light squared. However, I am not sure how to use it. When I have to calculate [itex]\frac{\sqrt{2mE}}{\hbar}[/itex], do I have to multiply m with the speed of light squared to get it in meters per second squared? Or, divide? Yes, I am a little confused.
PS. Energy is given in electronvolts, and Planck's reduced constant is given in electronvolt seconds.
