How to convert ounces of caster sugar to cups
Weight ounces first become grams (1 oz = 28.35 g), so 16 oz = 454 g. One US cup of caster sugar weighs 220 g, so 454 ÷ 220 = 2.06 cups.
Sugar is fairly consistent by volume, but sticky syrups cling to the cup – grease it first so you get the full amount out.
