Sour cream:
grams to cups.
Sour cream weighs 230 g per cup — slightly less than plain milk because its fat content and thick consistency mean it doesn't settle to a perfectly flat fill level in a measuring cup. For enriched cakes and dips where texture depends on fat content, grams give more precision.

Thick and spoonable: why cup measurement is less reliable for sour cream
Sour cream is thick enough to hold a spoon upright, which creates a problem for cup measurement: it doesn't self-level like a liquid. When you spoon sour cream into a measuring cup, you can easily leave air pockets at the base without seeing them from above, or you can overfill by pressing too firmly with the back of the spoon. The actual weight can range from 210 to 250 g depending on technique. For savory applications like tacos or dips, this variation doesn't matter. For pound cake or cheesecake where sour cream provides specific fat content and moisture, weighing 230 g removes the guesswork.
Full-fat vs reduced-fat: the density tradeoff
Full-fat sour cream (18–20% fat) weighs approximately 230 g per cup. Reduced-fat sour cream has fat replaced with additional water, making it slightly denser and thinner — closer to 235–240 g per cup. Low-fat or fat-free versions are more liquid still. The 230 g/cup conversion applies specifically to full-fat sour cream. In baking, fat-free sour cream substitutions change the fat content of the recipe significantly — by weight, you may be adding the same grams but a very different amount of fat, which alters texture and richness.
Frequently asked questions
- How many grams is ½ cup of sour cream?
- ½ cup of sour cream weighs 115 g (230 g ÷ 2).
- Is sour cream heavier or lighter than yogurt per cup?
- Lighter — sour cream weighs 230 g per cup, while Greek or plain yogurt weighs 245 g per cup. Yogurt is denser because it contains less fat and more protein per volume.
- How many cups is 250 g of sour cream?
- 250 g ÷ 230 g/cup ≈ 1.09 cups — just over 1 cup.
