All-purpose flour cups to grams converter
Use this all-purpose flour cups to grams converter when a recipe gives volume but you want the repeatability of a kitchen scale. The page is pre-filled with all-purpose flour and uses 120 grams per US cup as the working density, so cup, tablespoon, teaspoon, milliliter, fluid ounce, and gram conversions stay tied to the ingredient instead of a generic liquid assumption. Spoon flour into the cup and level it off; scooping from the bag can compact flour and raise the gram weight. It is most useful for cakes, cookies, quick breads, sauces, and general recipe scaling, especially when scaling a recipe up or down before mixing.

Frequently asked questions
How many grams are in 1 cup of all-purpose flour?
This page uses 120 grams for 1 US cup of all-purpose flour. Cup weights can vary by brand, grind, moisture, and packing method, so weigh the ingredient when precision matters.
Can I convert all-purpose flour tablespoons and teaspoons to grams here?
Yes. Choose tablespoons or teaspoons in the unit menu and keep all-purpose flour selected as the ingredient. The calculator uses the same ingredient density for the smaller volume units.
Why is all-purpose flour different from water in a cooking converter?
All-purpose flour has its own density, so a cup does not weigh the same as a cup of water. That is why this page keeps a dedicated ingredient setting instead of using one universal cups-to-grams factor.
What measuring note should I remember for all-purpose flour?
Spoon flour into the cup and level it off; scooping from the bag can compact flour and raise the gram weight.
