Sugar Conversion Chart: Grams to Cups
"Sugar" covers granular, liquid, and packed forms that can differ by more than 150 grams in the same cup. The chart below lines up the common sugars and sweeteners side by side, then breaks granulated sugar down by amount. Run any figure through the converter for an exact result.

The gap between sifted powdered sugar (100g/cup) and molasses (328g/cup) is over 200 grams in the exact same volume. Notice that packed and loose brown sugar are listed separately: they're the same ingredient, just two different states, and mixing them up is one of the more common measuring mistakes in this category. See what "packed" actually means for the full breakdown.
