How to convert ounces of caster sugar to cups
Weight ounces first become grams (1 oz = 28.35 g), so 1 oz = 28 g. One US cup of caster sugar weighs 220 g, so 28 ÷ 220 = 0.13 cups.
Sugar is fairly consistent by volume, but sticky syrups cling to the cup – grease it first so you get the full amount out.

Frequently asked questions
How many cups is 1 ounce of caster sugar?
1 ounce of caster sugar is about 2 tablespoons (0.13 cups), based on 220 g per level US cup.
Is it different with a UK or Australian cup?
Slightly. UK, Australian and New Zealand recipes use a 250 ml metric cup, which is about 6% bigger than a US cup (236.6 ml). In metric cups, 1 ounce of caster sugar is 0.12 cups.
Should I weigh caster sugar or measure it by volume?
Sugar is fairly consistent by volume, but sticky syrups cling to the cup – grease it first so you get the full amount out. Weighing is always more accurate, which is why grams are the safest choice for baking.
