How Much Is 3.09 Cups of Milk in Ounces?
3.09 cups of milk equals 26.60 oz. Milk has a density of 244g per cup (244g per cup), which means it's relatively heavy compared to other common cooking ingredients. For comparison, 3.09 cups of all-purpose flour would be 13.64 oz.
Formula and Step-by-Step
- Start with 3.09 cups of milk
- 1 cup of milk = 244g
- 3.09 × 244 = 753.96g
- Convert grams to ounces: 753.96 ÷ 28.3495 = 26.60 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Liquid densities vary: oils weigh less per cup than water, while syrups and honey weigh more. This is why ingredient-specific conversions matter even for liquids.

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?
An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.
