How Many Ounces Are in a Cup? Oz to Cups & Tbsp to Cups – Liquid & Dry Conversions

Knowing the right conversions for cooking, baking, and other household tasks is important. Whether you’re reading a recipe and need to know the conversions or want to know how many tablespoons or teaspoons are in a cup. You can read below for various conversions and use the tables as a converter.

What Is an Ounce?

An ounce (abbreviated oz) is a unit of measurement equal to 1/16th of a pound, or approximately 28 grams. An ounce is often used in the United States, the United Kingdom, and other countries that use the Imperial measurement system to measure weight and mass, with one ounce equal to approximately 437.5 grains. In the imperial system, an ounce is equal to approximately 1/12th of a pound.

However, the ounce, specifically the fluid ounce (abbreviated fl oz, fl. oz. or oz. fl.), also measures volume which is equal to about 28.4 ml of water. This is where confusion sets in. Sometimes recipes will simply refer to this unit as ounces, dropping the “fluid”, and even abbreviating it with just “oz.”

In most cooking situations where you are asked to measure liquid ingredients, you are generally asked to measure fluid ounces. On the other hand, if you are asked to measure dry ingredients, such as flour, you are probably being asked to measure weight and therefore traditional ounces.

What Are the Different Ounces? Dry Ounces vs. Liquid Ounces

Although dry ounces vs fluid ounces technically refer to weight vs volume respectively, conversions between the two are the same. Dry measuring cups will give you the same exact measurement as a liquid measuring cup. However, fluid measuring cups tend to be deeper and designed for pouring liquids while dry measuring cups are best for scooping up dry ingredients and scraping off excess.
