total armor rating???

hey all, i'm fairly new to these forums so hello to all!
i'm not so new to guild wars, been playing a month or so, and i have a lvl 18 Mo/R. Yes i know no matter how much i try my monk won't be a replacement for a warrior but i wanted to know if there's a way to see the final armor rating(% to be hit like in diablo) as it would be a great help in choosing echantments over armor rating or vice versa.
thanks for your help.

visit the game mechanics guide (adress below) says all you need to know, might be a little confusing though for some people
