How Much Is 4.45 Cups of All-Purpose Flour in Ounces?
4.45 cups of all-purpose flour weighs 19.65 oz. This is based on all-purpose flour having a density of 125.16g per cup. Because cups measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 4.45 cups.
Formula and Step-by-Step
- Start with 4.45 cups of all-purpose flour
- 1 cup of all-purpose flour = 125.16g
- 4.45 × 125.16 = 556.96g
- Convert grams to ounces: 556.96 ÷ 28.3495 = 19.65 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Humidity affects all-purpose flour weight. In humid conditions, flour absorbs moisture and weighs more per cup. Store it in an airtight container for consistent results.

Understanding the Units
What is a Cup?
In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.
What is an Ounce?
Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.
