How many cup in 1kg?

According to its label, a typical U.S. container of Oatmeal, such as Quaker Oats (about 4" in diameter and 7" tall), contains about 13 servings, each representing 1/2 cup of dry oatmeal, and weighs 524 grams. Therefore 1 kilogram of dry oatmeal represents: 1000 / 524 * 13 * 1/2 = 12 1/2 cups of dry oatmeal. (see discussion)
