Four cups of flour is a common measurement used in cooking and baking. Flour is a key ingredient in many recipes, including bread, cakes, and cookies. It provides structure and texture to baked goods. One cup of flour typically weighs about 120 grams, so four cups would weigh around 480 grams. When measuring flour, it's important to use the correct technique to ensure accuracy. Spoon the flour into a measuring cup and level it off with a straight edge, rather than scooping directly from the bag. This helps prevent packing, which can lead to using too much flour in a recipe.
