Why You Can't Use a Single Conversion Factor
There's no universal grams-to-cups conversion — every ingredient has its own density. A cup of flour weighs about 125 grams, but a cup of sugar weighs around 201 grams, and a cup of butter weighs 227 grams. Always pick the ingredient before converting, or you'll be off by a significant amount.
For ingredient-specific guidance, see the dedicated pages for plain flour, sugar, butter, or brown sugar.

Frequently Asked Questions
- How many cups is 100 grams of flour?

- How do I convert grams to cups?
- Divide the weight in grams by the weight of one cup of that ingredient. For example, 1 cup of plain flour is 125 grams, so 250 grams of flour is 250 ÷ 125 = 2 cups. The converter above does this automatically for any ingredient.
- Why does the same gram amount give different cups for different ingredients?
- Cups measure volume, grams measure weight. Denser ingredients like sugar or butter pack more weight into the same volume than light ingredients like flour or oats, so 100 grams of sugar takes up far less space than 100 grams of flour.
