All-Purpose Flour Cups to Grams Conversion
Converting all-purpose flour between US cups, grams, and ounces requires knowing its specific ingredient density. Unlike water (where 1 cup = 236.6g), dry and baking ingredients vary widely.

How to Correctly Measure Flour
Never scoop flour directly from the bag with your measuring cup — this compacts the flour and can add up to 25-30% extra weight (up to 150g per cup), resulting in dry, dense baked goods. Instead, fluff the flour with a fork, spoon it gently into the cup, and sweep the excess off level with the back of a butter knife.
Culinary Notes & Baker's Tips
For bread flour, 1 cup is slightly denser at ~127g. For cake flour, 1 cup is lighter at ~114g. If a European or UK recipe calls for "plain flour," 120g per cup is the standard conversion.
