I'm not sure I totally understand what you are asking, but.....

Here, mess around with this: http://hbd.org/cgi-bin/recipator/recipator

To answer your original question, each type of grain has a potential gravity associated with it. For standard American 2 row, it's 1.036. That means, if you grind it to flour, mash and convert completely, 1 pound of grain will yeild 1 gallon of wort at a gravity of 1.036. That's assuming you are 100% efficient, which is why it's called "potential". Every system will have a reduction in the actual gravity you get due to the efficiency factor.

To do the calculations yourself, use the following formula:

WG = (Lbs x PPG x Eff)/WV

WG = Predicted Wort Gravity in points like 45 or 50 or 60

Lbs = Pounds of grain used

PPG = Gravity potential of the grain (points per pound per gallon, i.e. 36 or 38 for typical base malt)

WV = Wort Volume in gallons

Eff = Your system efficiency

If you want a wort gravity of 1.060 in 1 gallon of water, and we'll assume 70% efficiency and a PPG of 36 for the grain, then your equation looks like this:

WG = 60

PPG = 36

WV = 1

Eff = 0.7

Solve for Lbs

Lbs = (60 x 1)/(36 x 0.7)

Lbs = 2.38 lbs

It's much easier for Promash to figure this for you, but an understanding of the math is good.

Prosit!
