Have you ever had moments when you stopped in your tracks while baking some delicious dessert recipes? It might be because you’ve poured the wrong ingredient into the batter, or because you realized you have no idea how many ounces in a cup there are. You’re not alone in this!

Check out our easy-to-understand measurement conversion guide that answers this very question and more. We also have some useful tips we think you’ll appreciate.

How Many Ounces In a Cup Conversion Guide

The first thing you have to understand when measuring ingredients for dessert recipes like, say, a no bake oreo cheesecake, is that liquid and dry ingredients are evidently not the same. When one is measuring liquid, the unit you’ll most likely be using is fluid ounces, and for dry ingredients, dry ounces.

Also, while a cup of water has the same volume and weight as a cup of coffee (since they’re both liquids), the same does not apply to dry ingredients like cheese, popcorn, or blueberries. That’s because not all dry ingredients’ shape or form is the same, and so not all of them take up space in the same way. Hence, why dry ingredients have different volumes. Ever wondered why dry ingredients are always measured using a kitchen scale? It’s because they’re usually measured by weight, not volume.

Not only that. As previously stated, even liquid and dry ingredients are also incomparable to each other. To put it into perspective, a cup or eight fluid ounces of coffee is not nearly the same volume as a cup of shredded cheese. A cup of cheese is only four dry ounces, while a cup of coffee is always eight ounces. So, how many ounces are there really in one cup? It depends. Are you measuring liquid or dry ingredients?

How Many Fluid Ounces In a Cup?

Let’s talk about this common question that’s often thrown around: how many fluid ounces are there in a cup? Now, this one’s easier to answer. There are exactly eight fluid ounces (oz) in a cup. A cup of water or coffee is always eight ounces. As we said, liquids are always comparable in weight and volume, that is why fluid ounces are the most accurate way to measure them.

Other than taking a peek at your handy conversion chart, you can also learn how to convert ounces to cup using a simple formula. When using this formula, keep in mind that one ounce is equal to .125 cups (1 ounce = .125 cups).

Given the formula number of ounces x .125 cups, here’s an example:

8 fl oz x .125 = 1 cup

32 fl oz x .125 = 4 cups

How Many Ounces In a Half Cup

Next, let’s talk about how many ounces in a half-cup there are. By this time, we know there are eight fluid ounces in a cup. So, in a half-cup, there are four fluid ounces.

How Many Ounces In a Third of Cup

While there are four fluid ounces in a half cup, a third of a cup has approximately 2.6 ounces. And much like you can convert ounces to cups, you can also convert cups to ounces using a formula.

To convert to ounces, multiply cup measurement (x) to eight. And then using a third of a cup (.33) x as an example:

.33 cups x 8 = 2.64 or 2.6 fl oz

How Many Ounces in a Quarter Cup?

This is also another question you’ll often hear. The answer to that is simply two fluid ounces in a US Standard cup.

How Many Dry Ounces in a Cup?

Converting dry ounces to a cup is not as straightforward as one might wish. As previously mentioned, dry ingredients are usually measured by weight because they tend to have different volumes (they occupy space in different ways—some more, and some less). However, dry ingredients can also have the same cup measurement (volume) and have different weights because of compressibility. Some ingredients, like flour (for example), are easy to jampack into a dry measuring cup. But ones like chocolate chips are not.

And so, even if you have one cup of flour and one cup of chocolate chips, they’ll be different in terms of weight. Why? Because you can pack flour, but you can’t do so as easily with chocolate chips due to their particular shape.

There are packed measurements for flour, sugar, and other similar ingredients too. But there are also ingredients that you can’t level with a bench scraper, like chocolate chips and blueberries. And so for these ingredients, don’t be afraid to fill the cup to the brim.

Liquid vs Dry Measuring Cups

Just because you’re measuring in cups doesn’t mean you use the same cup for liquid and dry measurements. There are different measuring tools for liquid and dry ingredients. Liquid measuring cups (also called graduated measuring cups) are used for fluid ingredients like milk, coffee, olive oil, and water. They’re usually made of glass with graduated markings that enable you to see how much liquid you’re pouring.

On the other hand, dry measuring cups are usually made with plastic or metal. And they also come in several measurements with cup measurements written on the handle. When you use dry measuring cups, take in mind that you have to level ingredients with a bench scraper or anything with a flat edge.

US Vs UK Measuring Cups

We talked about different measuring tools for dry and liquid ingredients, but depending on your country, liquid measuring cups can be slightly different too. A US Standard is 240 milliliters or 8.11 fluid ounces while UK cups measure 250 milliliters or 8.45 fluid ounces. A slight difference won’t affect most recipes, but if you’re bothered by this you can always check if it uses the US or UK measurement.
