Convert Cups to Grams: Sour Cream
Convert cups of sour cream to grams with this complete reference table. 1 cup of sour cream = 240g (USDA FoodData Central, spooned-and-leveled method). Use the table below for fractions from 1/8 cup up to 4 cups. For precision baking, weight measurements in grams are always more reliable than volume measurements in cups, because sour cream density can vary by measuring technique.
Sour Cream Cups to Grams Table
| Cups | Grams |
|---|---|
| 1/8 cup | 30g |
| 1/4 cup | 60g |
| 1/3 cup | 80g |
| 1/2 cup | 120g |
| 2/3 cup | 160g |
| 3/4 cup | 180g |
| 1 cup | 240g |
| 1 1/4 cups | 300g |
| 1 1/2 cups | 360g |
| 2 cups | 480g |
| 3 cups | 720g |
| 4 cups | 960g |
Based on USDA FoodData Central data (1 US cup = 240ml = 16 tablespoons = 48 teaspoons). Note: Sour cream is close to water density. 1 cup = 240g. Regular sour cream is 20% fat. Light sour cream is similar. Adds moisture and tang to baked goods. Can substitute Greek yogurt 1:1 in most recipes.
About Sour Cream Density
The density of sour cream determines how much it weighs per unit of volume. At 1g/ml, 1 US cup (240ml) of sour cream weighs 240g under USDA standard conditions.
Volume measurements can vary by ±10–20% depending on technique (sifted vs. spooned vs. scooped). For consistent baking results, use a kitchen scale with gram measurements whenever possible. The USDA standard (spooned-and-leveled) is the reference point for all values on this page.
Frequently Asked Questions
How many grams is 1 cup of sour cream?
1 cup of sour cream weighs 240 grams (USDA FoodData Central, spooned-and-leveled method, 1 US cup = 240ml).
How many grams is 1/2 cup of sour cream?
1/2 cup of sour cream weighs 120 grams.
