S.G. - F.G. Does this seem right?

[dexter_craig]

Starting gravity Was 1.058
Final Gravity was 1.018

ABV=9%

Is the coefficient 232?
Is this right?

Nope. Your ABV would be 5.2% with those gravities.

O.G. - F.G. * 131 = alcohol by volume.

Nope. Your ABV would be 5.2% with those gravities.

Right. and so you don;t have to post every time to ask (you know, "teach a man to fish", and all):



ABV = (OG - FG) x 131

ABV = (1.058 - 1.018) x 131 = 0.040 x 131 = 5.2%

Math...pfff.
I just punched it into beersmith. I'll have to add that formula to my arsenal as well.
