About All-Purpose Flour
All-purpose flour is the most common wheat flour for baking. One US cup of all-purpose flour weighs approximately 120 grams, which is why weighing flour on a scale gives far more consistent bakes than scooping by volume.
Whether you are scaling a recipe up, substituting an ingredient, or converting a recipe from metric to US measurements, having an accurate grams-per-cup value for all-purpose flour removes the guesswork from your cooking.

How much does a cup of all-purpose flour weigh?
A standard US cup of all-purpose flour weighs about 120 grams (4.23 ounces). That makes it almost the same weight as a cup of all-purpose flour, and lighter than a cup of granulated sugar (200 g). This is why a converter that uses the same factor for every ingredient will give wrong answers: all-purpose flour has its own density, and recipes depend on it.

Values are reference weights for level, unpacked measures unless the ingredient is normally packed. Brand, moisture, temperature and how firmly you fill the cup can shift the result by a few percent, so for precision baking weigh all-purpose flour on a kitchen scale and use the cup figure only as a guide. To understand why these numbers differ between ingredients, read our guide on why a cup of flour is not a cup of sugar, or see why weighing beats measuring cups.
