In everyday cooking and baking, understanding measurements is crucial. One of the most common questions is "How many ounces are is a cup?" Knowing the correct conversion between cups and ounces helps ensure recipe success, particularly when switching between different measurement systems like the U.S. customary system, metric system, and imperial system. This guide dives deep into these conversions, helping you confidently measure ingredients, whether for baking, cooking, or mixing beverages.
Understanding Cup Measurements in Different Systems
U.S. Standard vs. Imperial System
The U.S. customary system and the imperial system are often confused, but they measure volume differently. While a U.S. cup equals 8 fluid ounces, an imperial cup contains 10 fluid ounces. Understanding this distinction is critical when following recipes from different regions.
Metric System and Cups
Unlike the U.S. system, the metric system uses liters, but cups are still common in some regions. In the metric system, 1 metric cup equals 8.45 U.S. fluid ounces. Knowing this conversion will help when using international recipes.
What is An Ounce? What is a Cup?
An ounce (oz) is often used in the U.S. and the United Kingdom. You can understand that an ounce is a unit of measurement for weight. A unit of weight equal to approximately 28.35 grams.
A "cup" is a volume measuring unit that expresses how much space a substance occupies or how much it can contain. In the United States, a cup is equivalent to 8 fluid ounces; however, in other countries, it could be slightly different.
How Many Ounces is a Cup?
With fluid ounces, we have an exact per-cup measurement. However, to dry ounces, how many ounces in a cup will depend on what you are measuring. Because, dry ingredients have various shapes, sizes and forms.
For example:
- Flour - which weighs 4.5 ounces per cup
- Sugar - which weighs about 7 ounces per cup
For this reason the majority of dry materials for baking are also typically measured using a kitchen scale. Accuracy is ensured when measuring by weight rather than volume. But if a measuring cup is the only tool that you have, then knowing how many ounces in a cup will be helpful.
How Many Fluid Ounces in a Cup?
With liquid ingredients, it is easy to remember. Liquids are measured in fluid ounces, and there are 8 fluid ounces in 1 cup (this is applied to all liquids).
Let's see the liquid ingredient conversion chart below:
| Ounces (fl oz) | Cups | Milliliters (mL) | Tablespoons (Tbsp) |
| 2 fl oz | 1/4 cup | 59 mL | 4 Tbsp |
| 2 2/3 fl oz | 1/3 cup | 79 mL | 5 Tbsp |
| 4 fl oz | 1/2 cup | 118 mL | 8 Tbsp |
| 5 1/3 fl oz | 2/3 cup | 158 mL | 10 Tbsp |
| 6 fl oz | 3/4 cup | 177 mL | 12 Tbsp |
| 8 fl oz | 1 cup | 237 mL | 16 Tbsp |
| 12 fl oz | 1 1/2 cups | 355 mL | 24 Tbsp |
| 16 fl oz | 2 cups | 474 mL | 32 Tbsp |
| 32 fl oz | 4 cups | 948 mL | 64 Tbsp |
| 64 fl oz | 8 cups | 1896 mL | 128 Tbsp |
Look at this table, you can answer a lot of questions such as how many ounces are in a half cup, a third cup, and even a quarter cup, how many milliliters in a cup...
You can use this formula to multiply your cup measurement (x) by 8 ounces.
For example, how many ounces are in a quarter cup, a third of a cup, and a half cup:
- ¼ cup (or 0.25 cup) x 8 fl oz = 2 fl oz
- ⅓ cup (or 0.33 cup) x 8 fl oz = 2.64 or 2.6 fl oz
- ½ cup (or 0.5 cup) x 8 fl oz = 4 fl oz
How Many Dry Ounces in a Cup?
For dry ingredients such as sugar, flour, or oats, the standard measurement is a dry ounce. However, there is no exact answer for how many ounces are in a cup of dry ingredients.
For example:
- 1 cup of all-purpose flour = 128 grams or 4.5 oz.
- 1 cup of white sugar = 198 grams or 7 oz.

How to Measure Dry And Liquid Ingredients
There are some tools to measure dry and liquid ingredients such as liquid measuring cups, measuring spoons,....
Liquid Measuring Cup
Graduated measuring cups, often known as liquid measuring cups, are tools used to measure liquid ingredients such as water, milk, coffee, milk, etc.They're usually made of plastic or glass with graduated markings that let you see how much liquid you’re pouring.
Granulated/Dry Measuring Cup
Dry measuring cups are usually made of plastic or metal. When using dry measuring cups, you should sift your ingredients through a sieve or a baking sifted before measuring for a more accurate result.
Measuring Spoons
In the kitchen, measuring spoons are also a needed tool. There are a lot of cooking recipes that use tablespoons or teaspoons when listing ingredient quantities. Besides that, these spoons can be used for both dry and wet ingredients.
Should I Use Measuring Cups or Scales?
Cups can be used to measure liquid ingredients just as precisely as a measuring scale. Through the above sections, you already have an idea how many ounces are in a cup, so you can switch between the two as you wish.
However, you need to pay attention to how the recipe says you should prepare the ingredient. Because a cup of spinach that has been finely chopped will weigh more than loosely packed spinach. Or a cup of shredded cheese will weigh more than a cup of chunky cheese because you can fit more of it in.
If you want to measure exact amounts of ingredients, you should use measuring cups. In contrast, if you want to measure the weight of an ingredient or a dish, it is recommended to use scales.
