SG calculator

[Downwards]

So I have used various SG calculators and while I get a similar range from them, I'm getting different results with the same numbers.

Is one more accurate than another or does everybody just have preferences?

This one is interesting, has two different result depending on which calculation you want to use. Does that mean that one is more accurate than the other?

I always take starting SG - ending SG *133

Theres a lot of us here that use the calculator from Grape stompers as well.
