How to convert ounces of cornstarch to cups
Weight ounces first become grams (1 oz = 28.35 g), so 16 oz = 454 g. One US cup of cornstarch weighs 120 g, so 454 ÷ 120 = 3.78 cups.
Spoon flour into the cup and level it with a knife. Scooping straight from the bag packs it down and can add 20–30% more.
