I am having problems calculating my ABV ...
I had been using the formula (OG - FG) X 105 = ABV but my friend ( who are more experienced drinkers all tell me that the ABV is considerably higher than what I have calculated.
I have since checked online and found the following formulas ... also for determining ABV from the SG readings:
(OG - SG) X 131
(OG - SG) / 7.36
(OG - SG) / .75
(OG - SG) X 129
(OG - SG) / 7.69
Why are there so many different formulas and which one is correct?
