WebJun 28, 2013 · 244. 49. It's not entirely correct to say that the wavefunction requires certain units for the probability to work out. In fact, wavefunctions are quite agnostic about the units/dimensions used. This is because the state space is really a projective space, containing the C-rays and not C-vectors. This is not obvious because we are used to the ...
