How Much Is 1.39 Cups of Milk in Ounces?
1.39 cups of milk weighs 11.96 oz. This is based on milk having a density of 244g 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 1.39 cups.
Formula and Step-by-Step
- Start with 1.39 cups of milk
- 1 cup of milk = 244g
- 1.39 × 244 = 339.16g
- Convert grams to ounces: 339.16 ÷ 28.3495 = 11.96 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
For liquids, place your measuring cup on a flat surface and read at eye level. The bottom of the meniscus (the curve at the surface) should align with the measurement line.

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.
