Granulated Sugar Grams to Cups
Snapshot
100 grams of granulated sugar equals 0.51 cups. Conversion Encyclopedia keeps one fixed ingredient basis on this page so the calculator, common values, and reverse page stay aligned.
- Reference basis: 198 g per 1 US cup.
- Example: 250 g = 1.26 cups (about 1 1/4 cups).
- Use the reverse page if you need the opposite direction with the same basis.

}Explanation
Use the same 198 g per US cup reference to express granulated sugar weight as US cups.
Gram-based recipes and cup-based prep therefore use one explicit assumption. That is especially useful for baking, syrups, and dessert prep where sweetness and structure depend on repeatable weight. Very small gram amounts are too little to measure reliably in a cup, so cup measuring only becomes practical at larger weights. Granulated Sugar can vary with crystal size, moisture, and caking, so the page keeps one explicit basis instead of mixing packing styles.

Questions & answers
Frequently Asked Questions
How many cups is 100 g of Granulated Sugar?
100 g of Granulated Sugar is 0.51 cups (about 1/2 cup) using 198 g per cup.
Does this use the same factor as the Cups To Grams page?
Yes. The mirror page uses the same 198 g-per-cup factor, only in the opposite direction.
Does crystal size or packing change the result for Granulated Sugar?
Granulated Sugar keeps one reference basis here, but crystal size, moisture, and caking can shift how much fits in a spoon or cup. That matters more with sugars and sweeteners than with a purely liquid measure.
How many cups is 250 g of Granulated Sugar?
250 g of Granulated Sugar is 1.26 cups (about 1 1/4 cups) using 198 g per cup.
How do I convert Granulated Sugar cups back to grams?
Use the mirror Cups To Grams page; multiply cups by 198 to return grams.
