How Many Ounces In A Cup? (Conversions For Common Ingredients!)

This post contains affiliate links.

Need to know how many ounces are in a cup for a recipe? Or what is the difference between fluid ounces and dry ounces? Or how many grams are in a cup? This is the ultimate guide to measuring ounces, grams, and cups!

Solid measuring cups with oats, flour, and rice in them.

In cooking, and especially baking, precise measurements are often the difference between okay cooking and great cooking.

One key concept is weight vs. volume. We were raised to understand that there are 16 ounces in a pound and 8 ounces in a cup, but this is mixing up dry and liquid measures. Two different beasts entirely. 8 fluid ounces (a fluid cup) of water does weigh 8 ounces. But if you fill that same fluid cup with powdered sugar, it will not weigh 8 ounces.

Just because two things take up the same volume (like a cup), doesn’t mean they weigh the same (as in ounces). For example:

1 cup of popcorn = 0.3 ounces
1 cup of flour = 4.1 ounces
1 cup of chocolate chips = 6.0 ounces

So for precise baking, cooking, or converting, it’s important to know how many ounces are in a cup for whatever ingredient you’re using.

Most recipes will handle this for you requiring measurements like ½ cup of brown sugar. They are giving you the volume of brown sugar that the recipe needs. But, it is not uncommon to see a recipe ask for 100g of cocoa. They are asking for a specific weight (not volume).

If you don’t use a kitchen scale, what should you do? Fortunately, you’ve come to the right place!

How To Measure Cups

Cups are a very common unit of measurement in the USA, and are used to measure the volume of your ingredients. Sometimes we forget that there are dry cups and fluid cups, and each should be measured using different types of equipment. With either just be sure to set the cup on level surface to fill vs just holding it in our hand and eyeballing it.

How to measure ounces

There are dry ounces and fluid ounces, and each should be measured using different types of equipment.

Use your kitchen scale to measure dry ounces. If you don’t have one then scroll down to our ingredients charts giving you the weight in grams and ounces of all the most common ingredients when measured into cups

Your scale is, obviously, of no use in fluid ounces. Just break out a measuring cup calibrated in fluid ounces.

What would be 2.8 oz to equal how many cups. 0.7 equal cups? And 3.5. Equal cups?.I did the math but it not on pyrex measuring cup

1. Sarah Bond says:

  Hi Val! The cup measurement depends on the ingredient since different foods have different densities. For example, 2.8 oz of flour is about 2/3 cup, while sugar is closer to 1/3 cup, and liquids like water would be about 1/3 cup—let me know what you’re measuring for a more exact conversion!

  0.7oz for vegetable oil and 2.8 is for condensed milk ,3.5 whipping cream. Can’t find on pyrex measuring cup.
  Can you help me.
3. Sarah Bond says:
  
  February 4, 2025 at 6:34 pm
  
  Yes! For conversions: 0.7 oz of vegetable oil is about 1.5 tablespoons, 2.8 oz of condensed milk is roughly 1/4 cup + 1 tablespoon, and 3.5 oz of whipping cream is close to 1/2 cup. Since Pyrex cups usually measure in larger increments, using tablespoons may be more precise for small amounts!
