The formula is E = (1 / 4 pi E0) (q1 q2 / r12). Thus your conversion
factor is 1 / (4 pi E0) where E0
= 8.854 187 817... x 10-12 J^-1 C^2 m-1.
Sorry for the lack of typography.

I have the charges on the two atoms as -0.47 and -0.55. They are 3.15
Angstroms apart. So, E = (-0.55*-0.45)e-38 C^2/3.15e-8 m.
I get 8.21e-32 C^2/m. My question is how do I convert this to Joules?
