How Many Ounces Are in a Cup of Sour Cream?

How many fluid ounces are in 1 cup of sour cream?

1 US cup of sour cream equals 8 fluid ounces. This is the same fluid ounce count as any other ingredient measured in a US cup; fluid ounces measure volume, not weight, so the answer doesn't change based on what's in the cup. The 8 fl oz per cup relationship holds whether you're measuring sour cream, water, milk, yogurt, or any other liquid or semi-liquid ingredient. Sour cream is sold in containers sized in fluid ounces: standard sizes include 8 oz (1 cup), 16 oz (1 pint, 2 cups), and 24 oz (3 cups). The 8 oz single-cup container is convenient for recipes that call for exactly 1 cup of sour cream, which is one of the most common amounts in dips, baked goods, and topping applications.

How much does 1 cup of sour cream weigh?

1 cup of sour cream weighs about 230 grams (8.1 ounces by weight). The weight is slightly less than 1 cup of water (237 g) because sour cream contains air pockets from the culturing process and slightly less density than water. The 230 g figure is the standard reference for sour cream in baking, where weight measurements give more reliable results than volume. For nutrition tracking, 1 cup of regular sour cream (full fat) contains about 480 calories and 48 g of fat, while light sour cream contains about 280 calories and 24 g of fat.

How do sour cream measurements scale through cups and ounces?

For US cup amounts: 1 tablespoon is 0.5 fl oz (about 15 g), 1/4 cup is 2 fl oz (about 58 g), 1/3 cup is 2.67 fl oz (about 76 g), 1/2 cup is 4 fl oz (about 115 g), 2/3 cup is 5.33 fl oz (about 153 g), 3/4 cup is 6 fl oz (about 173 g), and 1 cup is 8 fl oz (about 230 g). For container sizes: an 8 oz container is 1 cup, a 16 oz container (pint) is 2 cups, and a 24 oz container is 3 cups. These container sizes match most American recipes, which typically call for 1, 2, or 3 cups of sour cream for dips and baked goods. For recipes using metric measurements, the gram conversion (230 g per cup) is the relevant figure.

When does the sour cream ounce conversion matter most?

Buying sour cream by the container is the most common case. Knowing 8 oz equals 1 cup helps match container sizes to recipe needs without measuring out portions. Recipe scaling benefits too: doubling a recipe with 1 cup of sour cream requires 16 oz (1 pint container), while halving requires 4 oz. International recipe conversion uses grams (230 g per cup), since European and Australian recipes list dairy ingredients by weight. Nutrition tracking for low-fat or low-calorie diets uses cup or gram measurements; light sour cream substitution maintains the same cup volume but reduces fat content.
