Grams to Cups Converter
Enter the weight in grams and select your ingredient — the calculator converts to cups using the ingredient's actual density, not a generic conversion ratio.
Select your ingredient and enter the weight — the calculator preloads grams → cups.
When to Convert Grams Back to Cups
You might need to convert grams back to cups if you only have measuring cups available, if you're sharing a recipe with someone who doesn't have a kitchen scale, or if you want to sanity-check a recipe that uses metric weights.
Keep in mind that grams are always the more accurate measurement. When you convert back to cups, tiny rounding errors can accumulate — especially for small quantities like baking soda or spices. If precision matters (e.g., for bread or pastry), stick with grams.
Frequently Asked Questions
How many cups is 100 grams of flour?
100 grams of all-purpose flour is approximately 0.8 cups (about ¾ cup plus 1 tablespoon). This uses a density of ~0.529 g/ml and a US customary cup of 236.6ml. The exact amount can vary slightly depending on how you measured the flour originally.
How many cups is 200 grams of sugar?
200 grams of granulated white sugar is exactly 1 cup using the US customary measurement. For brown sugar (packed), 200g is also approximately 1 cup. Powdered sugar is less dense — 200g of icing sugar is closer to 1⅔ cups.
Why do grams convert differently for each ingredient?
Because a cup measures volume, not weight. Each ingredient has a different density — how heavy it is per unit of volume. Dense liquids like honey (1.42 g/ml) weigh much more per cup than light flours like almond flour (0.41 g/ml). This calculator uses the specific density of each ingredient to give you an accurate cup equivalent.
