Some notes are that the ounces to cup conversion works for water and fluids with a high water content. This conversion will not work for "dry" goods such as flour, sugar, etc. or for chopped vegetables. Eight ounces in a cup and 16 in a pound, but they measure different things. A cup is measured by volume and a pound by weight. So you can't be sure that two cups of, say, flour, weigh a pound. In fact, they don't.
