I have noticed a few questions about converting from dry extract to syrup
or from all grain to extract. The easiest way to convert SG's is to know
what the yield of each item is and convert. If a recipe calls for a SG of
1.050 and one pound of dry malt yields 45 pts/gal = 9 pts/5 gal, you would
need 50/9 = 5.55 lbs of dry malt. Also if a recipe calls for 7 lbs of
grains which yields about 35 pts/gal (I know this is ideal, but you get
the idea) 7 * 35 = 245pts total, 245/45(pts for dry) = 5.44 lbs of dry
malt. I know this may be confusing, not the math but the way I have
explained it.

Here are two lists of yields which were posted previously (sorry for
stealing your work, but I hate typing and I did not want to make my own
list, so if there is any error don't blame me :-)).

===========================================================================

These are the numbers quoted by Dave Miller in his new book, "The Complete
Handbook of Home Brewing" (Garden Way Publishing, 1988). All numbers assume
1 pound of material in 1 gallon of water.

Barley Flakes...........30
Black Malt..............24
Cane Sugar..............45
Cara-Pils...............30
Corn or Rice Flakes.....40
Corn Sugar..............40
Crystal Malts...........24
Honey...................35
Malt Extract Powder.....45
Malt Extract Syrup......36
Mild Ale Malt...........33
Munich Malt.............33
Pale Ale Malt...........35
Roast Barley............24
Six-row Lager Malt......33
Two-row Lager Malt......35
Vienna Malt (homemade)..30
Wheat Malt..............38

===========================================================================

Ingredient Gravity for 1 pound in 1 US gallon Dry Malt
Extract 47
Malt Extract Syrup 40
Corn, Rice 39.5
Wheat Malt 39
English 2 row lager, pale 37.5
English mild ale malt 36
German 2 row pilsner malt 35
German 2 row munich malt 34.5
Light crystal, Dextrine malt 32.5
Brown, amber malt 32
US, Canadian 6 row lager malt 31
Chocolate malt, Dark crystal 30.5
Black malt, Roast barley 30

Note that these are theoretical MAXIMUMS. You won't get these in your
brewpot.

Sorry if letters are missing my system is not the best.
