For dry goods like all-purpose flour and confectioner's sugar, 180 grams is equivalent to approximately 1 1/2 cups or 6.5 ounces. Dry weight of foods and other items can vary slightly, so the same conversions do not apply to other items.
The weight of all-purpose flour converts at approximately 32 grams per 1/4 cup or 4 tablespoons and weighs about 1.13 ounces. However, bread flour is slightly denser than all-purpose flour, so it takes 34 grams to equal 1/4 cup, which weighs 1.2 ounces. Granulated white sugar is much heavier than confectioner's sugar, so it takes 50 grams to equal 1/4 cup, which weighs 1.78 ounces. Even denser is packed brown sugar, which is granulated sugar mixed with molasses. Brown sugar measures out to 55 grams for 1/4 cup, which weighs 1.9 ounces.
