I have read a half-dozen places where the simple formula for calculating alcohol percentage is:
Starting SG - Ending SG x (????) = % alcohol by weight.
The (????) figure ranges from 105 to 130 to 135.
What is the correct factor by which to multiply, in this simple formula???
I also heard that multiplying the a.b.w. figure by 1.25 would yield the a.b.v. percentage. True?
