The joy of homebrewing 3rd edition?

[kontrol]

I'm currently reading "The joy of homebrewing 3rd edition".

At some point the author says :

"10 determine alcohol content by means of the specific gravity scale, like* wise subtract the final specinc gravity from the original specinc gravity and multiply by 105 to get percent alcohol by weight. For example 1.040 - 1.010 = 0.030; thus, 0.030 x 105 = 3.15 percent.".

Isn't it * 131?.

Is this book any good? Because it's 400 pages + and I don't want to invest too many time reading a useless book lol.

....you been drinkin', huh?

Edit: and it really is an awesome read

My guess is Alcohol by Weight vs Alcohol by Volume. The former used to be more popular, but ABV is now more typical. And yes it's a good book.
