Is there a specific formula?

I've done some extract recipes in the past, just planning to get started with all-grain 1 gallon brews ..... I've seen some recipes for 5 gallon extract brews - is there a specific formula that can be used to convert an extract recipe over to all grain? Just a thought, since I don't want to have to parcel a can of extract over 5 different brews ;). I like the idea of 1 gallon brews becuz I can brew a different beer/style each time without having to down 5 gallons of my previous brew; I'm thinking that by brewing several/many 1 gallon recipes, I may find a favorite that I'll like enough to re-invest in a 5 gallon setup again.
Just my 2 centavos ........

Try a beer calculator

I recommend using a beer calculator. Try brewtoad (google it). You can enter a recipe for an extract brew, and then replace the extract with base malts to get the same color and gravity as before.

I primarily do 1 gallon

I primarily do 1 gallon batches, myself. I often try to locate 5 all-grain batches from a recipe book or at sites like http://www.homebrewersassociation.org/lets-brew/beginner/start-brewing/ and divide everything by 5. Other brewers might do this differently, but I usually pitch an entire packet of yeast into my jug and let it go.

Good luck with your small batches. It really is a great way to experiment without ending up with too much beer (if there is such a thing).

Well, after getting a

Well, after getting a consensus of opinions from several different forums and LHBSs; I'm still sticking to the 5 gallon number divided by1.333 (gives the equivalent of almost 1.5 gallons) in a 2.5 gallon jug. That helps to account for the trub, hydrometer tests (free samples), etc that still ends up with about 1 full gallon of brew. Anyone interested in conversion formulas for extract to grain, the only ones I've found were
1) multiply lbs/oz of DME by 1.667 = lbs/oz of grain
2) multiply lbs/oz of LME by 1.75 = lbs/oz of grain

Anyone who has a different formula, let me know, since this conversion rarely works out with BYO, Zymurgy, Extreme Brewing by Sam Calagione (great book, by the way), CloneBrews by Tess and Mark Szamatulski (sp?) book, etc.! Usually my conversion is higher by a pound or two from most books, which makes a stronger brew (and you know how I hate that lol, lol ). I got one homebrew book from a bookstore in TN, and the writer came up with the same grains from 3 different weights of DME in 3 different recipes. Either it was a stupid publisher or it was someone trying to rip off the public by sounding like an expert homebrewer. (Name with-held to protect the poor suckers that might buy one!).
