Very, very simple calculation
7D is 14.9mm x 22.3mm at 232 pixels/inch
So for any FF camera to EQUAL the 7D in a cropped image requires that you start with 232 pixels/inch...ergo the FF sensor needs to start with 232*(24x36mm) in order to be croppable to 232 pixels/inch at 14.9x22.3mm, or start with 5568 x 8532 on a FF sensor..but then the pixel size is equal, and therefore the noise level is likely equal was well.
Hmm mixing unit\'s of pixels/inch and mm is not usually wise. I assume you meant 232pixels/mm as your numbers are correct for the pixel sizes.
The calculation is even more trivial. 7D is a 1.61x crop sensor, so to get FF equivalent resolution it\'s 18*(1.61)^2 = 46.7MP.
