Sugar Grams to Cups Converter
Convert sugar grams to cups, cups to grams, or ounces to cups for granulated white sugar, packed brown sugar, powdered sugar, caster sugar, raw sugar, and superfine sugar.
Convert sugar by type
Pick the sugar first. A cup of powdered sugar weighs much less than a cup of packed brown sugar, so the type changes the answer.
For the most repeatable baking results, weigh sugar in grams. Cup estimates are still handy when a recipe gives only volume measurements.

Why sugar type matters
Different sugars settle differently in a measuring cup. Powdered sugar is fluffy, caster sugar is fine and dense, and brown sugar changes depending on whether it is packed.
This converter uses practical home-baking estimates. If a recipe says “packed brown sugar,” press the sugar into the measuring cup before leveling it.
