Convert Cups to Grams
Cups to grams for real ingredients — flour, sugar, butter and more — with a live, ingredient-aware converter.
Cups to Grams formula
Cups measure volume and grams measure weight, so the conversion runs through the ingredient's density. For flour (all-purpose):
grams = cups × 125.2 (for flour (all-purpose))
Worked example
1 cup of flour (all-purpose) = 125.2 grams.

Values use standard kitchen densities; real-world scooping and packing vary a little, so round sensibly when baking.

Frequently asked questions
How many grams is 1 cup of flour (all-purpose)?
About 125.2 grams. The exact figure depends on how the ingredient is scooped or packed, so treat it as a reliable baking estimate.
Why does the ingredient matter?
Cups measure volume while grams measure weight, and every ingredient has a different density — a cup of flour weighs far less than a cup of honey. Pick the ingredient in the converter to get the right factor.
Which cup and spoon sizes does this use?
US customary sizes: 1 cup = 236.6 ml, 1 tablespoon = 14.8 ml, 1 teaspoon = 4.9 ml. Metric cups (250 ml) will differ slightly.
