% ABV Question

Post by jcassady »

OK, let me see if I have this correct:
OG: 1.066
FG: 1.020 - (as expected)

= 5.9% ABV or did I miss calculate that horribly wrong?

I get 6.133%

No off by much ... My calculation is (omit decimal points)

take OG and subtract SG and divide by 7.5

thus 1066 - 1020 = 46 / 7.5 = 6.133...%

6.04%

1.066 - 1.020 = 0.046 x 105 = 4.83% Alcohol by weight

4.83 x 1.25 = 6.0375 % Alcohol by volume
