Converting 2.13 cups of all-purpose flour to ounces gives 9.40 oz. One cup of all-purpose flour weighs 125.16g, so 2.13 cups is 2.13 × 125.16 = 266.59g (9.40 oz). This conversion is specific to all-purpose flour because each ingredient has a different density.
Formula and Step-by-Step
- Start with 2.13 cups of all-purpose flour
- 1 cup of all-purpose flour = 125.16g
- 2.13 × 125.16 = 266.59g
- Convert grams to ounces: 266.59 ÷ 28.3495 = 9.40 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Different flour types have very different weights per cup. Always check the specific flour your recipe calls for rather than using a generic "flour" conversion.

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.
