Understanding the Basics of Ounces and Cups
What Are Ounces?
Ounces (oz) are a unit of weight measurement primarily used in the United States and some other countries. They are part of the imperial system and are commonly employed for measuring both liquids and dry ingredients. Ounces can refer to weight (avoirdupois ounces) or fluid volume (fluid ounces), which are different measures.
What Are Cups?
Cups are a volume measurement unit used primarily in cooking and baking, especially in the US. A standard US cup equals 8 fluid ounces when measuring liquids. However, dry ingredients may have different weights per cup, depending on their density.
Converting 120 Ounces to Cups: The Basics
Knowing whether you're dealing with fluid ounces or dry ounces is critical because the conversion varies.
Fluid Ounces to Cups
When converting fluid ounces to cups, the standard conversion is:
- 1 cup = 8 fluid ounces
So, to convert 120 fluid ounces to cups:
- 120 ÷ 8 = 15 cups
Therefore, 120 fluid ounces equal 15 cups.
Dry Ounces to Cups
Dry ounces measure weight, and converting to cups depends on the ingredient's density. For example, 1 cup of flour weighs approximately 4.25 ounces, whereas 1 cup of sugar weighs about 7 ounces.
Key point: Always check the specific ingredient's weight-to-volume conversion for dry ingredients.

How to Convert 120 Ounces to Cups for Different Ingredients
Because dry ingredients vary significantly in density, the conversion from ounces to cups is not universal. Here are common conversions for popular ingredients:
Flour
- 1 cup of all-purpose flour ≈ 4.25 oz
- To convert 120 oz of flour:
- 120 ÷ 4.25 ≈ 28.24 cups
Sugar
- 1 cup of granulated sugar ≈ 7 oz
- To convert 120 oz of sugar:
- 120 ÷ 7 ≈ 17.14 cups
Butter
- 1 cup of butter ≈ 8 oz
- To convert 120 oz of butter:
- 120 ÷ 8 = 15 cups
Oil
- 1 cup of oil ≈ 8 oz
- To convert 120 oz of oil:
- 120 ÷ 8 = 15 cups
Note: Always verify the specific ingredient's weight per cup for precise conversions, especially in baking.

Practical Tips for Converting Ounces to Cups
Use Accurate Conversion Charts
Having a reliable conversion chart for common ingredients can save time and prevent errors. These charts specify how many ounces equal one cup for various ingredients.
Invest in a Digital Kitchen Scale
A digital scale provides the most accurate measurement, especially for dry ingredients. Weighing ingredients directly in ounces and then converting to cups ensures precision.
Understand Ingredient Density
Different ingredients have unique densities, impacting the ounce-to-cup ratio. For example:
- Powdered sugar is lighter than granulated sugar per cup.
- Brown sugar packs differently than white sugar.
Use Consistent Measuring Tools
Use standard measuring cups and spoons to maintain consistency across measurements.
