Volume To Weight Conversion Estimate

I understand that there is no precise answer to my question, because a dry powder, such as flour will vary on weight depending on it's compaction and humidity, but I'm wondering if anyone can give me a close approximation of how much a cup of flour weighs? My new bread machine is scheduled to arrive tomorrow, and I need to buy some ingredients to test it out. Since I do not go to the store often, I need enough to make at least a dozen loaves, perhaps more, but don't know how much to buy.

1 cup =~ 125 grams.

Flour volume vs weight conversions | Grams | Ounces | Cups | Pounds | Kilograms | Quarts


125*12/2.2=3.3 bs.

Thanks, those values don't work well in my American set of weights and measurement, but in your link, I found that one cup = .27 lbs, so a 10 lb bag of flour should provide for ~ 37 loaves of bread, which would be plenty. I think that rye flour is somewhat heavier, but it should still work out close enough.
