ABV calculator
Alcohol by volume from original and final gravity, with both the simple and the high-gravity formula so you can see where they diverge.
ABV (simple)
5.25%
ABV (high gravity)
5.34%
Apparent attenuation
80.0%
Original extract
12.4 P
Model used
Standard (OG-FG)x131.25 and the Cutaiar alternate for strong beer. If another calculator gives you a different answer, this is usually why. Neither is wrong; they are different published models of the same process.
