1 cup flour in grams
All-purpose flour cups to grams converter
One cup of all-purpose flour weighs 120 grams when spooned and leveled — the measurement convention used in most modern recipes and by professional bakers. Scooping a cup straight from the bag packs more flour in and pushes the weight to about 142 g per cup, an ~18% difference that can break a recipe.

Convention
Two numbers? Here's why
Why two numbers? The cup-to-gram convention
How you fill the measuring cup changes the answer. Spooned and leveled means spooning flour into the cup and sweeping the top flat with a knife — what King Arthur Baking, the Doves Farm chart, and most modern American recipes assume (120 g/cup). Scooping the cup directly through the bag compacts the flour and gives ~142 g/cup, about 18% more. If your baked goods come out dense, dry, or tough, you are almost certainly scooping when the recipe expects spooned.

How we cross-checked these numbers
Each density value is cross-referenced against at least two independent published sources. When two sources disagree by more than 5%, both conventions are shown in the "Why two numbers?" block above instead of silently picking one.

Note on accuracy
KAF and Doves Farm both list 120 g/cup for spooned-and-leveled all-purpose flour (perfect agreement). The 142 g/cup 'scooped' figure is the KAF-published value for the dip-and-sweep / packed technique, which yields ~18% more flour per cup. Default is spooned & leveled, which is what most modern recipes assume.
