Help with grains, or help with math? Just kidding, but you are going to want like 2.9-3kg of grain. This is all dependent on your efficiency. I would recommend finding an online calculator or recipe builder (just do a quick google search and pick the one you like best). That will help you make sure you are hitting your desired gravity (and avoid division).
