For Example:
OG = 1036
FG = 1011
OK so the Coopers Book says this one:
(OG-FG) / 7.46 (plus 0.5% for priming)
So... (1036-1011)= 25
25/7.46 = 3.35% (or 3.85% after priming)
Others use this one:
(OG-FG) x131
So... (.036-.011)=0.025
0.025x131 = 3.27%
If the OG was 1055 and FG was 1010, the 1st method 6.03% (6.53% priming) the 2nd would be 5.90%. So quite a bit different.
Iv heard some Homebrew Books say to add 0.3% for priming, Coopers is 0.5%. What is a more accurate number? The bottle size shouldn't make a difference?
