How Many Ounces Are In A Cup?

Hi there! That’s a great question. Knowing how many ounces are in a cup is very helpful when reading or adapting recipes. It’s important to note that there is a difference between fluid and dry ounces, so make sure you’re aware of which measurement you’re dealing with. In terms of liquid ingredients, a cup of liquid is equal to 8 fluid ounces (fl. oz) or 240ml.

However, for dry ingredients, it’s a different story. A cup of sugar, for instance, weighs more than a cup of flour, yet they take up the same volume (1 cup). Dry ingredients are measured by weight, not volume, and this is where ounces come into play. To figure out how many ounces are in a cup, you'll need to check the weight of the specific ingredient you’re dealing with. To help you with this, I’ve included a helpful chart below that outlines the most common conversions when dealing with ounces in a cup. When all else fails with weight use a baking scale.

Believe it or not this is one of the most Googled questions on the web!

1 tablespoon (tbsp) = 0.5 ounce (oz)

1 cup = 8 ounces (oz)

1/4 cup = 2 ounces (oz)

1/3 cup = 2.66 ounces (oz)

1/2 cup = 4 ounces (oz)

2/3 cup = 5.33 ounces (oz)

3/4 cup = 6 ounces (oz)

I hope this helps! #cookinginmyboots David Locke, REALTOR, Cooking and Gardening Blogger
