Have you ever been in the middle of cooking a recipe and realized that you don’t know how to convert different units of measurement? In this article we’ll demystify measurements once and for all – starting with one of the most common conversions: how many ounces in a cup? The answer? It depends. Are you measuring dry ingredients or fluid ounces? Are you using American measuring cups vs British vs Australian measuring cups?

Measuring cups on a banner that says "How many ounces in a cup?

It’s confusing right?

There are a lot of recipes sites out there and it’s difficult when they use different measuring systems. Some use the imperial system and others use the metric system. Also the US Cup is different than the Imperial System Cup because we just love to do our own thing….yikes.

Did you know that 1 US Cup and 1 UK Cup are totally different? Did you know the the “Metric Cup” is now mostly defunct but it was different from both of the above measurements? I didnt until I started this website.

I get questions about weight and measurement a lot in my Keto Almond Yeast Bread Recipe so I thought this would help.

In this post we’ll go over how to convert both systems and there are conversion charts further down to help.

After reading, it’ll be a piece of cake.

But, if you are just here to find out how many ounces in a cup or the conversion chart…scroll on by and get it. I won’t force a whole cooking lesson on ya. (Psst, it’ll make it easier if you understand a few basics though).

Liquid and Dry Ingredients:

Liquid and dry ingredients are different because liquid ingredients are more dense than dry ingredients, meaning that a liquid measurement will always be a larger (heavier) quantity than the same volume of  dry weight. Think of it like this, the dry weight of a cup of cereal is always less than a cup of cereal with milk added. Liquid ingredients always weigh more but take up less space than dry weight.

In other words, liquid is calculated by volume and dry ingredients are usually calculated by weight.

For example, one tablespoon of liquid (such as water) is equal to three teaspoons, while one tablespoon of a dry ingredient (such as sugar) is equal to only two teaspoons. Because liquid ingredients are denser than dry ingredients, liquid will usually weigh more than the same volume of a dry ingredient. That is why dry and liquid measurements are not interchangeable in baking recipes.

But here in the US, we MOSTLY cook and bake using measuring cups and spoons instead of scales. So asking, how many ounces in a cup is dependent on what is being measured.

Knowing the difference between dry and liquid measuring is essential for making sure that your recipes turn out just the way you want them to. By understanding the difference between liquid and dry measurements, you can make sure that your ingredients are measured properly and produce consistent results every time!

Now that you know why liquid and dry measurements are different, it’s time to dive into how many ounces in a cup! With this knowledge, you’ll be able to measure liquid ingredients and dry ingredients correctly and make sure that your recipes turn out perfectly every time. So let’s get started!

Liquid Measuring Cup

Liquid measuring cups are designed for measuring liquid ingredients and other liquid mixtures. These cups usually come with a pouring spout for ease and markings on the side to indicate measurements in ounces, milliliters, or liters.

Some liquid measuring cups can also be used to measure both fluid ounces and dry ingredients like flour and sugar, as they have a dry ingredients measurement line marking different volumes of these ingredients.

The liquid measuring cup is an essential tool used in many cooking and baking recipes, as it ensures accuracy when baking. It also allows for easy conversions between dry and liquid if needed. With its versatility and convenience, the liquid measuring cups are a must-have item for any home cook.

How many fluid ounces in a cup – Liquid Measurements:

Since I am based in the US I will be talking about a US Cup here. There are 8 fluid ounces in a cup. And it makes it easy if you can remember the simple formula that 2 tablespoons equal 1 ounce.

  • 16 cups = 1 gallon = 128 fluid ounces = 3.78 liters

Dry Measuring Cups:

A dry measuring cup measures volume solid ingredients such as flour, sugar, and nuts. It is typically made of metal or plastic and has marked measurements on the side. Unlike liquid measuring cups which are filled up to the desired measurement line, measuring cups for dry ingredient should be filled to overflowing and then leveled off with a spatula for accuracy.

The proper way to do this is to spoon the ingredient into your measuring cup and then level it off.

You shouldn’t just scoop the ingredients out out the bag, box or tin with the measuring cup if you are baking and trying to be very precise.

Properly measuring your ingredients is key to achieving delicious Keto Desserts and Low Carb Bread.

How Many Ounces in a Cup- Dry Ingredients:

Well that depends on what you are measuring.  Cups to ounces can vary greatly.  For instance, 4 ounces of almonds will have a different volume than 4 ounces of almond flour.

Measuring Tablespoons and Teaspoons:

The Metric System and Imperial System tablespoons are slightly different in that Imperial tablespoons measure slightly less than metric measuring spoons. They are used to measure both wet and dry ingredients.

An Imperial tablespoon holds roughly 14.8 milliliters (ml) of a liquid, while a metric measuring spoon is 15 ml.

But, an imperial tablespoon= 3 teaspoons (which are the same in both metric and imperial.)

  • 1 tablespoon = ½ fluid ounce = 3 teaspoons = 15 ml
  • 2 tablespoons = 1 fluid ounce = 6 teaspoons = 30 ml
  • 4 tablespoons = 2 liquid ounces = 12 teaspoons = 59 ml

How do you measure butter?

Butter isn’t normally measured in it’s liquid state but it isn’t dry either. Still, it’s measured in fluid ounces and 1 cup of butter = 8 ounces.

I have a lot of recipes that contain butter and since there are different measurement systems being used by my readers, this one comes up a lot. One poor soul was frustrated and asked how the heck do you measure solid butter by the tablespoon? 

Here in the US, our butter comes in 1/2 cup (4 ounces) portions with lines on the package so we can easily cut off as many tablespoons as we need. 

  • 1/4 cup = 2 fluid ounces = 4 tablespoons = 1/2 stick of butter
  • 1/2 cup = 4 fluid ounces = 8  tablespoons = 1 stick of butter
  • 1 cup = 8 ounces = 16 tablespoons = 2 sticks of butter

But don’t think this applies to all “butters”. Nut butter weighs in at about 9.5 ounces per cup. You can use this handy tool to find the weight and volumes tons of different ingredients.
