whenever I plug in the correct values I don't get 1. Unless I'm supposed to use au.

Well what is Coulomb's constant?

Am I correct in assuming that e is the elementary charge?

 

[yungwun22]

it's 1/(4*pi*episolon naught) where episolon naught is 8.85 x 10^-12 F/m. yes, e is the elementary charge.

Then there is nothing left to do since as you have now pointed out in your edited opening post, it is clear that

$$e^2 \cdot\kappa \neq 1$$
