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:
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.
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.
Cups to ounces for common ingredients
It’s important to know how many ounces are in a cup for each individual ingredient you’re cooking with, because the weights can vary so greatly! The information below is provided to give you simple conversions for commonly used ingredients.

Other Useful Measurements
Cups and ounces are just small parts of the world of measurements! Here are more common measurement conversions that you may need:
Here are the basics to convert ounces to fluid cups (which measure liquid ingredients): 1 cup = 8 fluid ounces. ¾ cup = 6 fluid ounces. ½ cup = 4 fluid ounces.
Here are the basics to convert ounces to fluid cups (which measure liquid ingredients): 1 cup = 8 fluid ounces. ¾ cup = 6 fluid ounces. ½ cup = 4 fluid ounces.
In the US, 1 cup is equal to 8 fluid ounces. This conversion is widely used and not just for recipes. For liquids, 1/2 cup is 4 fluid ounces, 1/4 cup is 2 fluid ounces, and 1/8 cup is 1 fluid ounce.
There are 4.5 ounces of dry ingredients in a cup. How many cups are in a gallon? There are 18.62 cups in a gallon when it comes to dry ingredients. There are 16 cups of liquid in a gallon.
1 cup of water weighs 236 grams.1 cup of flour weighs 125 grams. The volume is the same, but the weight is different (remember: lead and feathers). One other benefit to using metric measurements is accuracy: scales often only show ounces to the quarter or eighth of an ounce, so 4 1/4 ounces or 10 1/8 ounces.
Liquid needs to be measured by the bottom of its meniscus (the curve that forms on the top of liquid). But the meniscus can't be properly measured in a dry measure, since you must fill the dry measure right to the top with the liquid. The bottom of the meniscus is thus concealed.
there are 8 oz.per cup. Divide 8 by 4 and you have your answer. It doesn't matter if it's sour cream, heavy cream, light cream, butter, water, or any other liquid measure.
A cup of all-purpose flour weighs 4 1/4 ounces or 120 grams. This chart is a quick reference for volume, ounces, and grams equivalencies for common ingredients.
8 dry ounces is a specific volume of 1 cup. 16 dry ounces is 1 (dry) pint (by volume). A quart (32 ounces) of (dry) beans weighs less than a quart of vinegar (which has a mass slightly higher than a quart of pure water).
Here's a good rule of thumb to follow — when measuring dry ingredients, use dry measuring cups or weigh them with a scale. For liquids, stick to a liquid measuring cup.
If you are measuring with measuring cups, pour the ingredients in the cup and check if they are level with the graduation on the cup from the side. Make sure to keep your face to the eye level with the cup for an accurate measurement. If you are looking at it from above, your measurement will be incorrect.
Officially, a US Cup is 240ml (or 8.45 imperial fluid ounces.) This is slightly different from an Australian, Canadian and South African Cup which is 250ml. As long as you use the same cup for measuring out each of your ingredients, the proportions should work out the same.

So 2 ounces divided by 8 equals 1/4 cup. If you only have teaspoons, you multiply the number of ounces by 6. To convert 2 ounces to teaspoons, this would equal 12 teaspoons.
There are 4 1/2 dry-weight ounces in one cup. This, too, is according to the US system. With dry ingredients, it's important to remember that they need to be measured by weight.
