How Much Is 8 Ounces of Sour Cream in Cups?
8 ounces of sour cream equals 0.99 cups. Sour cream has a density of 230g per cup. A lighter ingredient like flour (125g/cup) would fill more volume at the same weight, which is why ingredient-specific conversions matter.
Formula and Step-by-Step
- Start with 8 ounces of sour cream
- Convert ounces to grams: 8 × 28.35 = 226.80g
- 1 cup of sour cream = 230g
- 226.80g ÷ 230g/cup = 0.99 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
