We started getting conversion requests the day we published the cups-to-grams page — people needed it in the other direction because European and Asian recipes list ingredients in grams while their kitchen drawers are full of American cup measures. The catch is that grams-to-cups is not a fixed ratio the way millilitres-to-cups is: King Arthur Baking's ingredient weight chart puts all-purpose flour at 120 grams per cup, granulated sugar at 198 grams, and honey at 340 grams, all filling the exact same 236.6 millilitres of space. Plug 200 grams into a generic converter and it tells you 0.85 cups regardless of what you are measuring — which is dead wrong for flour and dead wrong in the opposite direction for honey.
Here is the number that makes the problem concrete: 250 grams of flour fills about 2 cups, but 250 grams of sugar fills only 1.25 cups — same weight, wildly different volume. The math itself is straightforward: divide grams by the ingredient's grams-per-cup density value. But tracking down accurate density data for 50-plus ingredients and doing that division every time you cook is nobody's idea of fun, especially mid-recipe with flour on your hands. The USDA's FoodData Central database publishes density values for thousands of food items, and our converter pulls from that data so you get a real answer based on measured ingredient density rather than a one-size-fits-all water estimate.

Frequently Asked Questions
How many cups is 100 grams of flour?
100 grams of all-purpose flour equals about 0.80 cups (roughly ¾ cup + 1 tablespoon).
How many cups is 250 grams of sugar?
250 grams of granulated sugar equals 1.25 cups (1 cup + ¼ cup).
Why do European recipes use grams instead of cups?
Grams are more precise. Weight doesn't change with how you scoop or pack an ingredient, making recipes more consistent and reproducible.
Can I convert grams to cups for any ingredient?
Our converter supports 50+ common cooking ingredients. For unlisted ingredients, you can use water's density (237g per cup) as a rough estimate for liquids.
