FAQ
How many ounces is 1 cup of caster sugar?
1 cup of caster sugar is about 7.94 ounces, based on a standard weight of 225 grams per US cup.
Why do gram weights for caster sugar vary between recipes?
Volume measurements depend on how the ingredient is packed. Spooned-and-leveled caster sugar weighs less than scooped. Our values use standard baking averages, so brands and techniques may differ by a few percent.
Is it better to measure caster sugar by weight or volume?
Weight. A kitchen scale removes packing errors entirely, which is why professional recipes list grams. Use this table to convert older volume-based recipes.
