Conversion formula
Converting grams to cups uses one simple formula. Because a cup measures volume and a gram measures weight, the formula needs the ingredient's density expressed as grams per cup:
Example: 200 g of all-purpose flour ÷ 120 g/cup = 1.67 cups. The grams-per-cup value differs for every ingredient — that is why the same weight of flour, sugar, and butter produces different cup values. Pick your ingredient in the calculator above and the correct value is applied automatically.
About Grams to Cups
This grams to cups tool uses a precise per-ingredient grams-per-cup value stored in our database. Because a cup is a unit of volume and grams measure weight, the same number of grams produces a different cup value for each ingredient — flour, sugar, butter, honey, and oil all have different densities that we account for automatically.
Choose your ingredient from the dropdown, enter the value you want to convert, and the calculator instantly shows the equivalent measurement in the other unit. You can swap between grams and cups at any time using the Swap button without re-entering the ingredient selection.
All calculations happen locally in your browser, so the tool is fast, private, and works even on a slow connection after the initial page load. There is no need to refresh the page or call any external API to get your result.
