It seems like there are several different formula's floating around which allow you to calculate the ABV - some more complicated than others. The simplest one I've seen is:

ABV = (OG-FG) * 131

Just wondering if that's the "HBT approved" formula, or if there's another one? Thanks!

That's it. Anything else you've seen is either (a) the same formula stated differently (b) a formula for % alc by weight rather than volume or (c) wrong
