Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 230g/cup = cups
  1. Start with 8 ounces of sour cream
  2. Convert ounces to grams: 8 × 28.35 = 226.80g
  3. 1 cup of sour cream = 230g
  4. 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

Thickness varies between brands. Full-fat, low-fat, and non-fat versions can have slightly different weights per measuring cup.

Understanding the Units

What is an Ounce?

An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.

What is a Cup?

A cup is a US customary unit of volume equal to 236.588 milliliters or 8 fluid ounces. It is the most common volume measurement in American recipes. One cup can be divided into 16 tablespoons or 48 teaspoons.

Frequently Asked Questions

About 0.99 cups, based on sour cream having a density of 230g per cup. The exact amount depends on how the ingredient is measured and the specific product.
First convert ounces to grams (1 ounce = 28.3495g), then divide by 230 (grams per cup). For 8 ounces: 8 × 28.3495 = 226.80g, then 226.80 ÷ 230 = 0.99 cups.
For the most accurate results, weigh sour cream on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring cup and level it off with a straight edge rather than scooping directly.
Fat content has a small effect on density. Higher-fat versions are slightly lighter per volume because fat is less dense than water. The difference is usually under 5%, so this conversion works well for standard varieties.
Reverse the conversion: 0.99 cups × 230g/cup = 226.80g, then 226.80g ÷ 28.3495 = 8 ounces. Or use the Cups to Ounces converter.
