Approximately 21 Cups
There are roughly 21 cups in 453 grams of flour. This conversion is based on the standard US cup measurement, which is approximately 240 grams. While the exact number can vary slightly depending on the type of flour and how it's packed, 21 cups is a reliable estimate for baking purposes.
Methods for Measuring Flour
- Volume Measurement (Cup): This is the most common method. Use a standard measuring cup and level off the top.
- Weight Measurement (Gram): Using a kitchen scale provides the most accurate results. Weigh 240 grams of flour.
- Scoop and Level: Scooping flour directly from the bag can compact it, leading to an overestimation. Always spoon flour into the cup and level it off.

Factors Affecting Volume
- Flour Type: Whole wheat flour, for example, tends to pack more tightly than all-purpose flour.
- Humidity: Humidity can affect the density of flour.
- Packing: Over-packing the measuring cup will result in a larger volume.
Note: For precise baking, especially in recipes where flour quantity is critical, using a kitchen scale to measure by weight is highly recommended.
