Quick Answer
Yes, a 16 oz container of sour cream is equivalent to 2 cups. There are 8 fluid ounces in 1 cup. So a 16 oz container, which is 16 fluid ounces, equals 2 cups.
Detailed Answer
When converting between fluid ounces and cups, it’s important to remember that there are 8 fluid ounces in 1 cup. This conversion is useful to know when substituting ingredients in recipes or when trying to determine how much of an ingredient you have if it’s labeled in a different unit of measure.
Specifically, a 16 oz container of sour cream contains 16 fluid ounces of sour cream. To convert fluid ounces to cups, we divide by 8 (since there are 8 fluid ounces per cup):
16 oz ÷ 8 oz/cup = 2 cups
So a 16 oz tub of sour cream contains 2 cups of sour cream. Some key points:
- There are 8 fluid ounces in 1 cup
- To convert fluid ounces to cups, divide by 8
- A 16 oz container has 16 fluid ounces
- Dividing 16 oz by 8 oz/cup equals 2 cups
This information is useful for cooking and baking recipes that call for sour cream. Instead of needing to use multiple smaller containers, a 16 oz tub contains exactly 2 cups so you can measure out what you need directly from the container.
Cups to Ounces Conversion
The same logic applies in reverse when converting cups to fluid ounces:
- There are 8 fluid ounces in 1 cup
- To convert cups to fluid ounces, multiply by 8
So if a recipe calls for 4 cups of sour cream, we can determine how many fluid ounces that equals:
4 cups x 8 oz/cup = 32 fluid ounces
This tells us that 4 cups of sour cream is equal to 32 fluid ounces. Being able to convert between cups and ounces in both directions is handy for substitution and measurement.
Comparing Volume vs Weight
One thing to keep in mind is that the 16 oz measurement on a container of sour cream refers to the volume (fluid ounces) rather than the weight (ounces). For example:
- 16 fluid ounces (volume) = 2 cups
- 16 ounces (weight) ≠ 2 cups
So if you’re substituting sour cream by weight instead of volume, you’ll need to do a separate conversion to determine how many cups are in 16 ounces by weight. But for a typical 16 oz tub of sour cream, those 16 oz refer to volume, which equals 2 cups.
Metric Conversions
For bakers and cooks using the metric system, here are some handy conversions for 250ml and 500ml containers of sour cream:
- 250ml = 1 cup
- 500ml = 2 cups
So a 500ml tub of sour cream contains 2 cups just like a 16 oz tub in the US customary system. Knowing metric conversions can be useful for adapting recipes from different countries.
Bottom Line
The short answer is: Yes, a 16 oz tub of sour cream contains 2 cups of sour cream. This conversion is helpful to know when sour cream is called for in recipes or you need to substitute it for another ingredient.
To summarize:
- There are 8 fluid ounces (oz) in 1 cup
- To convert ounces to cups: Divide fluid oz by 8
- A 16 oz container has 16 fluid ounces
- 16 oz ÷ 8 oz/cup = 2 cups
So a 16 oz tub or container of sour cream equals 2 cups.

| Container Size | Fluid Ounces | Cups |
|---|---|---|
| 16 oz | 16 | 2 |
| 32 oz | 32 | 4 |
| 8 oz | 8 | 1 |

Storing and Handling Sour Cream
Once opened, sour cream should be properly stored in the refrigerator to maximize freshness. Here are some tips:
- Keep sour cream refrigerated at 40°F or below
- Store opened container towards the back of the fridge
- Replace lid tightly after each use
- Use within 7-10 days for peak quality
- Don’t freeze full container of sour cream (freezes texture)
- Freeze individual portions or incorporate into recipe first
Properly storing and handling sour cream prevents waste and keeps it fresher longer. And a 16 oz tub equals 2 handy cups for all your cooking, baking, and topping needs.
How to Soften Hard Sour Cream
If your previously opened sour cream has been in the fridge for a while, it can harden and become difficult to use. Here are some tips for softening hardened sour cream:
- Use a spoon to stir and “break up” chunks
- Mix in a splash of milk to thin out consistency
- Let sit at room temperature for 10-15 minutes
- Avoid microwaving which can curdle or separate cream
- Stir gently to reach smooth, creamy texture
With a little work, hardened sour cream can be reconditioned for using in dips, baking, topping baked potatoes, and more. Just be sure to refrigerate it again after softening.
Common Uses for Sour Cream
With its cool, tangy taste, sour cream is a versatile dairy product used in both sweet and savory dishes. Here are some of the most popular ways to use sour cream:
- Dips – Mix with onion soup mix or seasoning for chips and veggies
- Toppings – For baked potatoes, chili, tacos
- Baking – Add to cakes, cookies, muffins, and breads
- Sauces – Thickens and adds flavor to gravies and savory sauces
- Frosting – Combines nicely with cream cheese
Sour cream adds a cool contrast to spicy foods, provides richness to sweets, and helps bind ingredients together. It’s a refrigerator staple! Now you know that convenient 16 oz container equals 2 cups.
Cooking Substitutions for Sour Cream
Don’t have any sour cream on hand? Try one of these substitutions in your cooking and baking:
- Plain Greek yogurt – Thick and tangy like sour cream
- Buttermilk – Adds tang but is thinner
- Plain yogurt + lemon juice – For flavor and acidity
- Creme fraiche – Similar cultured cream product
- Mayonnaise – Only in small amounts in dips, won’t work for baking
Each substitution will work a bit differently, so adjust other ingredients as needed. Greek yogurt is often the closest replacement for sour cream in terms of texture and tanginess. But other dairy products can work in a pinch!
How Long Does Sour Cream Last?
Properly stored, sour cream lasts:
- Unopened – About 3 weeks past the “best by” date
- Opened – About 7-10 days in the fridge
To extend sour cream’s shelf life, keep refrigerated at all times and reseal the container after each use. Look for signs of spoilage like mold, off smell, curdling, or separation of liquid.
A 16 oz tub or 2 cup container is a convenient size that typically gets used up well within the 7-10 day window. But unused portions can be frozen for later use in baking recipes too.
Whipping Sour Cream
Whipped sour cream has a lighter, fluffier texture perfect for topping desserts or making dips. Here’s how to whip it:
- Chill bowl and beaters to help it set
- Add 1 cup cold sour cream and 1/4 tsp cream of tartar
- Whip on high speed for 1-2 minutes
- Fold in sugar or other flavors as desired
- Refrigerate 1 hour before serving
The cream of tartar helps stabilize the whipped cream. Try substituting a dash of vanilla or citrus zest for extra flavor. Pretty and practical!
Make Your Own Sour Cream
Want to DIY? You can make easy homemade sour cream with just two ingredients:
- 1 cup heavy cream
- 2 tbsp lemon juice or white vinegar
Directions:
- Combine ingredients in a jar or bowl
- Let sit at room temperature 8-12 hours
- Stir well before refrigerating
- Use within 10 days
The acidity helps thicken and sour the cream. Customize the flavor with lime juice or experiment with yogurt starters. Making your own only takes a bit of planning.
