"what google has taken into consideration while it is going to converting links into backlinks" You mean, What links do Google count as Back links right? All links without no follow tag are back links.
no doubt it counts all the back links, even if it gives 0 points to some back links. here is what i think you are looking for. 1- relevancy 2- <50 links on a page 3- anchor text 4- quality of linking page, and landing page not all but some of them should work
Google don't care if the links is dofollow or nofollow, if they think it's relevant and good links they count the links. But you can't really see the true number of your links just by using google command, view all your links on google webmaster tool.
