What is the difference between pKA and KA for in terms of acidity?

I believe that KA stands for the equilibrium constant for an acid, and pKA provides the -log of the concentration of KA. pKA provides you a way to compare other pKAs if that makes sense....

Let's say a KA = $10^{-10}$
pKA = 10

and a KA = $10^{-8}$
pKA = 8 (so this is a stronger acid than the previous one)
