- TL;DR Summary
- Would have thought cgs and SI would give the same debye length when converted to the same units, but they don't. What is the physical meaning difference, and how do I know which equation to use.

Hello - I am trying to understand the physical meaning the undergirds the Debye length as it pertains to different unit systems. I understand that fundamentally its the distance at which the distribution of ions doesn't differ by more than the effect of k_B*T from the rest of the solution, plasma, whatever. But what I don't understand is why cgs and SI can give such radically different values. If they just came out as different values with different units, whatever. But I can convert both to meters, and get completely different numbers. I'm writing a review article, and this isn't really my field, but all the papers I came across had different expressions, and I dug a little deeper, and found this confusion, and I don't know how to resolve it. I'd just be somewhat vague, but I don't even know how to kindof defend the choice of one or the other equation, other than saying, "everywhere else I used SI," which isn't a very good answer.
