Lets say I mass a standard 12oz bottle of beer, just the liquid not the bottle. (specific gravity of this beer= 1.0113)  The scale reads 384.7g.  How do I convert this to a liquid volume.  I thougt I could convert the grams to ounces and then devide by specific gravity but it didn't look correct.  I got 13.42 fluid oz.  But I belive it to be closer to 12.2-12.4.  Any help would be much appriciated.  ???
