Calculating Target OG for GF Brews

[igliashon]

Anybody know how to calculate the contributions to gravity that liquid sorghum, brown rice solids, honey, candi sugar, molasses, etc. make? I've been thinking I may be brewing at excessively high gravities, since I typically use 6-7 lbs of fermentables plus 2 lbs of adjuncts in my 3-gallon batches, but I don't really know how to get an exact number. I mean, my goal is definitely to brew high-gravity brews, and so far they've seemed to ferment just fine, but it would be nice to be able to put some numbers (even ballpark numbers) to what I'm doing.

Google brew calculus...or maybe its beer calculus. Online calculator that has alot of ingredients...

BYO mag also has a tool here http://byo.com/resources/grains?gtype=6
I think I remember seeing a spreadsheet on the Home brew wiki at one point as well
