Cups of Flour in Grams by Flour Type
One US cup of all-purpose flour is about 125 g using this site’s spoon-and-level convention. Bread, cake and whole wheat flour have different reference weights; use the recipe author’s gram amounts when supplied.

Reference values are approximate; use measured weights and your recipe’s stated conventions where available.
Scale your ingredient list
Replace the example with your ingredients, one quantity per line. This multiplies amounts; it does not convert ingredient densities or determine baking time. Suggested multiplier for this guide: 1.5. Enter it in “Multiply by.”
Use one measurement convention throughout
These are approximate US-cup conversions from our existing ingredient weight chart, not fixed physical constants. Spoon flour lightly into the cup and level the top without packing it. A cup dipped into the bag can hold more. Cup size, milling and settling also matter. Do not replace an author’s tested weight with this chart simply because both are labeled one cup.
Convert before multiplying
For 2½ cups of all-purpose flour, calculate 2.5 × 125 = 312.5 g. For a half batch, use 156.25 g before practical rounding. Enter the gram amount in the scaler to resize the recipe. The scaler multiplies quantities; it does not infer the density of an ingredient from its name or automatically turn cups into grams.
Flour weights do not make flours interchangeable
The chart answers how much a measured volume weighs. It does not make almond flour, coconut flour or cake flour a one-for-one substitute for bread flour. Protein, starch and absorption affect structure. When changing flour type, follow a tested substitution or recipe rather than matching only the gram total.
Frequently asked questions
Is a cup of flour always 125 grams?
No. This is our approximate all-purpose reference; recipes and measuring methods differ.
How many grams are 3 cups of all-purpose flour?
About 375 g under the 125 g per US cup convention.
Should I sift before measuring?
Follow the recipe’s order. Sifting changes how much flour fits in a cup.
Does the scaler convert cups to grams?
No. Convert with the chart or cups-to-grams tool first, then scale.
