What is Ounce?

Ounce (Oz) is a unit of weight, mass, or volume primarily used in the United States’ customary and imperial systems. In terms of measurement, 1 oz = 28.35 g (grams) or 0.029 kg (kilograms). In the US, the most common ounces are liquid ounces and dry ounces – with each having its own separate measurements.

In general, liquid ounce measurements are used to calculate liquid ingredients, while dry ounce measurements are typically used for non-liquid items such as baking ingredients. Now that you know what an ounce is, let’s figure out how many ounces in a cup!

How Many Ounces In A Cup?

The answer to this question depends on what you’re measuring, as the measurements for a cup of liquid and a cup of dry items differ.  

 How Many Fluid Ounces in a Cups?

Liquids, for example, milk, water, oil, and juice are measured in fluid ounces (fl oz). So if you want to know how many ounces in a cup for liquid measurements, the answer is 8 fluid ounces per cup, in another word, 1 cup = 8 fl oz.

This formulation is the same for all liquid measurements, regardless of whether you’re measuring a hot cup of coffee or an icy glass of iced tea.

How Many Dry Ounces in a Cup?

For dry ingredients (egs: sugar, flour, or oats) the standard measurement is a dry ounce (oz). But, there is no definitive answer for how many ounces are in a cup of dry ingredients because the density of each item can vary significantly. Generally, depending on the ingredient, one cup of a dry ingredient can weigh anywhere from 4 to 8 ounces.

For example, 1 cup of all-purpose flour is equal to 128 grams or 4.5 oz, while 1 cup of white sugar is equal to 198 grams or 7 oz. 

Different Measurement Systems for a Cup

The measurements of a cup may differ in different countries or even from one measurement system to another. In the United States, one cup is equal to 8 fluid ounces (fl oz), while in the UK, 1 cup is equal to 10 fl oz. For those who prefer the metric system, 1 cup is equal to 250 ml of liquid or 8.45 oz. 

Therefore, it’s important to double-check the measurements to ensure your results turn out correctly. 

How to Convert From Ounces to Cups

Now that we know how many ounces are in a cup, let’s talk about converting from ounces to cups. This can be useful when you need to quickly figure out the equivalent measurements for an ingredient without measuring it out first.

To convert Ounces to Cups in US measurements, divide the number of ounces by 8. For example, if you have 24 ounces, this would be equal to 3 cups (24/8 = 3).

For easy reference, here is a simple converting chart to help you figure out how many ounces are in a US cup:

• ¼ Cups =  2 Ounces = 60 mL = 4 tablespoons
• ½ Cups = 4 Ounces = 120 mL = 8 tablespoons
• ¾ Cups = 6 Ounces = 180 mL = 12 tablespoons
• 1 Cup = 8 Ounces = 250 ML = 16 tablespoons
• 1 ½ Cups =  12 Ounces = 375 ML = 24 tablespoons
• 2 Cups = 16 Ounces = 500 ML = 32 tablespoons
• 3 Cups = 24 Ounces = 750 ML = 48 tablespoons
• 4 Cups = 32 Ounces = 1000 ML = 64 tablespoons
• 5 Cups =  40 Ounces = 1250 ML = 80 tablespoons

If you’re using the metric system or UK measurements, divide the number of fluid ounces by 10 to get your answer for converting Ounces to Cups (for example, 120 fl oz / 10 = 12 cups).

For easy reference, here is a simple converting chart to help you figure out how many ounces are in a UK cup: 

• ¼ t Cups =   2.5 Ounces = 75 mL =  5 tablespoons
• ½ Cups =  5 Ounces = 150 mL = 10 tablespoons
• ¾ Cups = 7.5 Ounces = 225 ML = 15 tablespoons
• 1 Cup = 10 Ounces = 300 ML =  20 tablespoons
• 1 ½ Cups = 15 Ounces = 450 ML = 30 tablespoons
• 2 Cups = 20 Ounces = 600 ML = 40 tablespoons
• 3 Cups = 30 Ounces = 900 ML = 60 tablespoons
• 4 Cups = 40 Ounces = 1200 ML = 80 tablespoons
• 5 Cups = 50 Ounces = 1500 ML = 100 tablespoons

What Is the Difference Between Liquid and Dry Measurements?

As mentioned before, liquid measurements are typically calculated using fluid ounces (fl oz), and dry ingredients are measured by dry ounces (oz). The difference between the two systems is that the fluid ounce measurement measures volume, while the dry ounce measurement accounts for weight.

Therefore, if you’re measuring a cup of liquid, it will always be 8 fl oz, regardless of the item. However, for a cup of dry ingredients, the amount will vary depending on how much the ingredient weighs.

Cup for Measuring Liquids

A liquid measuring cup is usually made of plastic or glass, with a spout on one side to aid pouring. The surfaces usually have markings that indicate measurements in cups, ounces, liters, and milliliters. 

To fill in the cup,  make sure the liquid is at eye level and slowly pour until it reaches the desired measurement. Read off the markings on the cup to determine how many ounces are in a cup of liquid ingredients. In addition,  using measuring spoons and cups can also help you get accurate measurements.

Cup for Measuring Dry ingredients

A dry measuring cup is usually metal with flat rims and a curved bottom. The surface also has markings that indicate measurements in cups, ounces, tablespoons, and teaspoons. 

When using a dry measuring cup for ingredients such as sugar or flour, use the scoop-and-level method – dip the cup into the ingredient until it’s overflowing, then level the top with a knife or spoon. Read off the markings on the cup to determine how many ounces are in a cup of dry ingredients.

Should I Use Measuring Cups or Scales?

Measuring cups and scales both serve different purposes. Measuring cups are great for measuring specific volumes of ingredients, such as liquids or dry items like flour and sugar, while scales are better suited for measuring the weight of an ingredient or a dish.

If you’re trying to measure exact amounts of ingredients, it is recommended to use measuring cups. However, if you’re trying to measure the weight of an ingredient or a dish, it is best to use scales.
