Need to know how many ounces are in a cup for a recipe? Or what the difference is 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!
In cooking, and especially baking, precise measurements are often the difference between an 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, 8 ounces in a cup, etc. What we sometimes confuse, however, is that weight and volume are two different beasts.
Just because two things take up the same volume (like a cup), doesn’t mean they weight the same (like 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. Fortunately, you’ve come to the right place! Click the links below to jump around this ultimate guide, or scroll on to learn all about measuring cups and ounces:

How To Measure Cups
Cups are a very common unit of measurement in the U.S., and are used to measure the volume of something. There are dry cups and fluid cups, and each should be measured using different types of equipment.
Measuring Dry Cups
To measure dry things with cups – like flour, oats, or rice – use measuring cups meant for solids. Simply scoop the ingredient into the cup, the level it off.
Measuring Liquid Cups
To measure liquid things with cups – like water, milk, or oil – use liquid measuring cups. To measure liquids, place the liquid measuring cup on a flat surface and pour in your ingredient until it reaches the line for the amount you need.
How to measure ounces
Ounces are one of the most commonly used units of measurement in cooking and baking, and is a method for measuring the weight of something. There are dry ounces and fluid ounces, and each of which can be measured using different types of equipment.
Measuring Dry Ounces
To measure dry ounces, you will need a measuring cup or scale that is calibrated to measure in dry ounces. This type of measurement typically involves weighing dry ingredients such as flour, sugar, or grains. You simply place the dry ingredient into the measuring device and read off the weight displayed on the scale or look at how much is left in the cup after filling it up with dry ingredient.
Measuring Fluid Ounces
To measure liquid ounces, you will need a liquid measuring cup or graduated cylinder. This type of measurement typically involves pouring liquid ingredients such as oil or water into the measuring device. You simply pour the liquid until it reaches the desired level and then read off the measurement markings on the side of the cup or cylinder.
