Caster Sugar Measurement Converter
Use the tool below to convert caster sugar from Cup to Cup (US).
Caster sugar, also known as superfine sugar, is a key ingredient in many baking recipes due to its fine texture and quick-dissolving properties. Commonly used in cakes, meringues, and desserts, it sits between granulated sugar and powdered sugar in terms of texture.
Since baking is a precise science, even small differences in sugar quantity can affect the final outcome, from texture and sweetness to structure. This page helps you convert caster sugar between grams, cups, tablespoons, and more so that you can follow any recipe confidently, no matter what measurement system it uses.

Standard granulated sugar has larger crystals than caster sugar, so it dissolves more slowly in batters and meringues. They are close in weight (201 g vs 220 g per cup) and swap 1:1 by volume in most recipes, though caster gives a smoother result. See our Sugar converter.
Raw sugar has large, coarse crystals that dissolve slowly, the opposite of fine caster sugar. It packs lighter (200 g vs 220 g per cup), so it is not a 1:1 swap by volume; weigh when substituting. See our Raw Sugar converter.
