<<Disclaimer: Verify this information before applying it to your situation.>> In great excitement, I downloaded and unzipped this program, only to find that it still does not answer any questions about cups. The conversion is between cups and fluid (volume) ounces not weight ounces as we use here in the UK. The problem with volume measure of powders is that the actual weight of material you measure varies widely depending on the fineness/coarseness of the material you are measuring by volume. The difficulty can be demonstrated by the fact that I have measured two different rice flours which I use because they are respectively fine and coarse and have different properties in the cooking. The fine one weighed in at 330 grams for 2 cups, while the coarse one was 450 grams for 2 cups. Worse still the coarse one would pack down until I could get 500 grams in! Now considering that there is no reason to expect similar size of grind between two countries (size of sugar grains in Denmark and England are significantly different making some of the old Danish recipes which use volume much too sweet with English sugar), this makes it quite difficult to work out what the correct mix is. I might be measuring 50% more or less than you and that is likely to be a problem with non-GF cooking let alone GF cooking where I find I have to be MUCH more precise. (I have given up bothering with recipes in US cup measure as it takes several goes to get them right. This costs both a lot of time and also a lot of waste of food - something I consider immoral). The other thing I find astonishing is that in this modern day anyone voluntarily uses cup measure for dry ingredients, when an electronic kitchen scale is so much easier (mine will even measure in metric or imperial!). Why even a man can do it :-) All you do is measure out the first ingredient, press zero and measure the next on top - and so on..... Oh yes - and it is QUICK.
