Default Why does it seem so confusing to convert?

HI, I'm building a European trainer kit called a Parat for my kids. Because I hate emergency room visits I decided to build this as my first electric ( yeah I got a few stitches when I was 12). The old kit came with a gigantic can style motor which everone said to put in a truck or the garbage. I don't want to sound like a moron but I'm confused as to what to buy for power and control ( it's already a difficult build due to metric/sae conversions and German to English translations). Anyhow this plane has a 48 inch wingspan give or take a millimeter or 2 and a 36 inch fuse. I'm building it with strip ailerons and no dihedral. It looks alot like a Sig Kadet but smaller, The wing is almost identical but scaled down. The plans state the weight of the electric version @ 1320 grams and the nitro version @1060 grams . The nitro version of this plane calls for a .09-.15 Cu. In. engine (if I did my coversions right). I thought given the extra weight incurred by batteries that a .20 cu. in. nitro would be just right so I went to the hobby shop and said give me a brushless motor that will preform like a 20 size nitro. I thought it would be simple but I left confused and without a motor or speed control. Don'tget me wrong the hobby shop owner was cool and advised me to build the plane and bring it in then we could find the best power alterantive but it bugs me when I can't understand something that seems like it should be simple.
Is there some sort of simple converion table for nitro to electric?
Any suggestions as to how to power this plane would be appreciated !
What is the most bang for the buck in electric power?
