Why granulated sugar has its own cups-to-grams number
Granulated (white) sugar pours freely and doesn’t compress much, so a level cup is fairly consistent from kitchen to kitchen. It is also heavy for its volume — a cup weighs well over a cup of flour — which is why you can’t use one cups-to-grams number for every dry ingredient.

How to measure granulated sugar for this conversion
- Scooping is fine for granulated sugar; just sweep the top level.
- Don’t pack it down. Packing is only for brown sugar.
- Superfine (caster) sugar and coarse sanding sugar have different crystal sizes, so their cup weights can differ from this reference value.
- When a recipe gives sugar in grams, weighing directly into the bowl on a tared scale saves washing a cup.
