How to Convert Units for Coulomb's Law Equations

[QUOTE="kh199, post: 4531923, member: 490605"] I have a real simple question. I'm doing a problem that involves Coulomb's law. My charge separation is 5 nanomeers, and the charges are each elementary. So, for the equation, I have: (9E9 [B](N*m^2/C^2)[/B] *(1.6E-19)^2 [B](C^2) [/B]) / (5 [B]nm[/B])^2 Units are bolded. The denominator has to be converted to meters to it can cancel out with the units of K. Do I have to square the x10^-9 multiplier as well? Does the denominator end up as 2.5E-8 [B]m^2[/B] or does it end up as 2.5E-17 [B]m^2[/B] [/QUOTE]
