Sugar Grams to Cups Converter
Convert granulated sugar grams to US cups and back.
Convert granulated sugar by a clear convention
Granulated sugar has a more consistent cup weight than flour, but crystal size and measuring practice still create variation. This page uses 200 grams per US cup, a common kitchen convention. It is specifically for granulated sugar rather than packed brown sugar or powdered sugar.
The default 200 grams converts to exactly 1 US cup under this convention. Reversing direction returns 200 grams for 1 cup. Decimal inputs support recipe scaling, such as half a cup converting to 100 grams, without forcing the result into kitchen fractions.
Local recipe conversion with ingredient scope
All amounts stay in your browser. The page does not read a recipe or infer sugar type. For confectioners sugar, coarse crystals, or packed brown sugar, use a source-specific weight because substituting this granulated-sugar factor can noticeably change a recipe.
