How to convert ounces of caster sugar to cups
Weight ounces first become grams (1 oz = 28.35 g), so 12 oz = 340 g. One US cup of caster sugar weighs 220 g, so 340 ÷ 220 = 1.55 cups.
Sugar is fairly consistent by volume, but sticky syrups cling to the cup – grease it first so you get the full amount out.
