How to understand our stats...

Legionary Class : Templar

I placed this toppic here but it aplies to all classes.

I asked about already once in the chat during the game but will ask again. Could you please write down any conversion equiations for character statistics?
Right now everything stand in raw numbers that doesn't tell how much it is in %. We all (I assume that all) know that % values are much easier to imagine and understand.
I am not sure if the same conversion rate states for all statistics or just for one but surely it is something I am looking forward to see.

E.g. 500 physical resistance = x % demage absorbed
50 critical chance = x % Critical chance

and so on.
