I have 2 questions regarding the conversion of hte 6.72kg of Weyermann Bohemian Pils malt: 1) What do you recommend that I use as an extract? Amber Extract? I don't know enough. 2) Since the brewer is assuming 90% effeciancy, do I need to adjust my correction factor of 0.6 for dry, or 0.75 for liquid? I don't know much about all-grain and 90% seems to be an exceptionally good sugar extraction. Let me know if I'm at all on base. How big of a difference will there be between the grains? I recently tried one of these tasty beers and loved it and want to make something similar.
 
yea, if your using a brewing program like beersmith or promash you can hit your efficiency lock button and it will adjust the amount of each grain in the recipe based on % of each malt as used in the recipe for your new eff.

Dont they make Pils extract?
 
At 90% eff, with your recipe, I get a OG of 1.046:
Amount Item Type % or IBU
14 lbs 13.0 oz Pilsner (2 Row) Bel (2.0 SRM) Grain 95.18 %
6.0 oz Carafa III (525.0 SRM) Grain 2.41 %
6.0 oz Caramunich Malt (56.0 SRM) Grain 2.41 %

Beer Profile
Est Original Gravity: 1.046 SG

Converting to LME, I get:
Amount Item Type % or IBU
14 lbs Pilsner Liquid Extract (3.5 SRM) Extract 94.92 %
6.0 oz Carafa III (525.0 SRM) Grain 2.54 %
6.0 oz Caramunich Malt (56.0 SRM) Grain 2.54 %

Beer Profile

Converting to DME, I get:
Amount Item Type % or IBU
11 lbs 8.0 oz Extra Light Dry Extract (3.0 SRM) Dry Extract 93.88 %
6.0 oz Carafa III (525.0 SRM) Grain 3.06 %
6.0 oz Caramunich Malt (56.0 SRM) Grain 3.06 %

Sorry, don't know how to do the math, but I know how to use Beersmith! Hope this helps.

If you need to convert back to metric, use google. www.google.com , type in, (for example) "6 oz in grams" or "11 lb + 8 oz in grams"
 
Thanks for the quick responses. I appreciate it. Regarding the pils malt, I don't know if they do or not. I don't remember seeing it at my LHBS, so I figured I'd ask.
 
Okay, too much beer in my belly/head to figure out all the math. It was my understanding that there would be NO math!

However, I would look for a pilsner extract or a light/pale extract to substitute for a portion of the pilsner malt. I don't think amber would be the right choice. Then again, the first partial mash I ever did is still about two weeks out!!
