    I have some charts for converting LME to grain, but few are similar. I have the brewing classic styles book, and the conversion they're using is yet another one.

    Do I go by what's in the recipe book or should I follow a standard conversion? And, where can I find a standard conversion for LME --> grain (and others like DME --> grain and vice versa).

    I know in the front of BYO magazine they have the correct conversion each month but I don't have that handy at the moment. This site seems to have a good representation of the conversion and explanation. The reason you may see a slight difference in your references is because the DME and LME are usually given as a range, so someone could be choosing a number in that range different from someone else, but they should be very close to each other.

    Wait, I just thought of this... is there a tool in Beersmith that can do the conversion for me?

    Divide instead of multiply. Or vice versa.

    Remember it is all about your efficiency...

    LME is ~37PPG on average

    Most 2-Row is also ~37 PPG, but you only get 75% (or your efficiency) of that. So to convert take the # of LME and divide by your efficiency and replace with 95% 2 Row & 5% Carapils (the standard LME)
