Cups to Ounces Sour Cream Cooking Size Chart
This chart converts sour cream between cups and ounces, covering 9 measurements from cups 1/8 up to cups 2. Because sour cream has a specific density that differs from other ingredients, these conversions apply only to sour cream — do not use them for other ingredients.
In baking and cooking, precision matters. A recipe calling for cups 1/8 of sour cream needs exactly ounces 1.0 — using a conversion for a different ingredient could throw off the balance of your recipe. Our chart accounts for the actual weight-to-volume ratio of sour cream.

How to Measure Your Ingredients Size
For dry ingredients, spoon the ingredient into the measuring cup and level off with a straight edge — never scoop directly from the bag, as this packs the ingredient and adds up to 20% extra weight. For liquids, use a liquid measuring cup (with a pour spout) and read at eye level on a flat surface. A digital kitchen scale is the most accurate option and eliminates the need for volume conversions altogether.
Tips for Converting Sour Cream Cooking Sizes
Weight-based measurements (grams, ounces) are more accurate than volume measurements (cups, tablespoons) for baking. Professional bakers almost always weigh ingredients.
Humidity, packing density, and grain size all affect how much of a dry ingredient fits in a cup. Two people measuring '1 cup of flour' can end up with weights differing by 30 grams.
When a recipe gives both weight and volume, always prefer the weight measurement — it is what the recipe developer used.

Frequently Asked Questions
- How do I convert sour cream from cups to ounces?
- Use our sour cream conversion chart above. For example, cups 2/3 of sour cream equals ounces 5.4. The chart covers 9 measurements so you can find the exact conversion you need.
- Does sour cream weigh the same as other ingredients per cup?
- No. Each ingredient has a different density, so 1 cup of sour cream weighs a different amount than 1 cup of flour, sugar, or any other ingredient. That is why ingredient-specific conversion charts like this one exist — using a generic converter will give inaccurate results.
- Should I measure sour cream by weight or volume?
- Weight (grams or ounces) is more accurate for baking because volume measurements like cups can vary by up to 20% depending on how the ingredient is scooped and packed. If your recipe gives both, always prefer the weight measurement. A digital kitchen scale is the most reliable tool.
- What is the smallest sour cream conversion in this chart?
- The smallest measurement in our chart is cups 1/8 of sour cream, which equals ounces 1.0.
- What is the largest sour cream conversion available?
- The largest measurement covered is cups 2 of sour cream, which converts to ounces 16.2. If you need a larger quantity, multiply the appropriate row from our chart.
- How do I measure sour cream accurately for baking?
- For cups, use the spoon-and-level method: spoon sour cream into the measuring cup, then sweep a straight edge across the top to level it off. Never scoop directly from the container — this packs the ingredient and gives you more than the recipe intended. For grams or ounces, use a digital scale set to zero (tared) with your bowl on it.
- Can I use this chart for sour cream in savoury recipes too?
- Yes. The weight-to-volume ratio of sour cream is the same regardless of whether you are baking or cooking a savoury dish. These conversions apply to any recipe that calls for sour cream.
