Dickason book and in it there is a table showing the Mmr for a given Sd; for example: for Sd=0.0165 square meters, Mmr=1.2 grams. But if I calculate: (0.0165 ^1.5) x 0.575 , the result is 0,0012. What am I missing? Thanks

However, it appears that you are off by a factor of a thousand. Perhaps the answer is given in kilograms instead of grams? Just guessing.
