One tablespoon of sour cream weighs 14.4 g (poured, USDA). Sour cream sits in the middle of the dairy weights — lighter than cream cheese, heavier than milk — because it is cultured cream with about 20 percent fat and a thick, spoonable texture that still pours slowly. The tablespoon figure is the one you reach for when a recipe calls for a spoonful or two to finish a sauce, enrich a batter, or top a baked potato, and you want to know what that means in grams. It is also the number that matters for nutrition tracking, since a tablespoon of sour cream carries roughly 30 calories. All weights on this page are approximate; sour cream varies slightly by brand and fat content, so verify with a scale when it matters.
How much does 1 tablespoon of sour cream weigh?
One level tablespoon of sour cream weighs 14.4 g, poured, according to USDA. That is the headline number, but a single tablespoon is rarely the whole story — most recipes use several spoonfuls, or a fraction of a cup, so the table below gives the weights you will actually reach for, from a teaspoon up to a full cup. Every figure is derived from the same source value of 230 g per cup, so the whole table is consistent. Treat all of these as approximate: poured is a technique, not a machine setting, and two cooks measuring the same ingredient can differ by a gram or two per spoonful. When the recipe matters, weigh the ingredient on a kitchen scale instead.
| Amount | Weight (approx.) |
| --- | --- |
| 1 teaspoon | 4.8 g |
| 1 tablespoon | 14.4 g |
| 2 tablespoons | 28.8 g |
| 3 tablespoons | 43.1 g |
| 1/4 cup (4 tbsp) | 57.5 g |
| 1/2 cup (8 tbsp) | 115 g |
| 3/4 cup (12 tbsp) | 172.5 g |
| 1 cup (16 tbsp) | 230 g |
A useful rule of thumb: there are 3 teaspoons in a tablespoon and 16 tablespoons in a cup, so you can move between any of these measures by multiplying or dividing. If a recipe calls for 2 teaspoons and you only have a tablespoon measure, that is two-thirds of a tablespoon — about 9.6 g. If a recipe calls for a quarter cup and you only have a tablespoon, that is 4 level tablespoons. Keep the tablespoons to grams converter open while you cook and you will never need to do the arithmetic in your head.
Worked examples
Finishing a beef stroganoff
A stroganoff for four is finished off the heat with 4 tablespoons of sour cream stirred into the sauce — about 58 g. The weight matters here because sour cream is the difference between a silky sauce and a split one. Too much, and the sauce turns thin and overly tangy; too little, and it never gets that gentle richness. Weighing 58 g also helps you add it gradually: stir in half, check the flavour, then add the rest. And because the pan is off the heat, the sour cream stays smooth instead of curdling, which is the real risk with this ingredient.
A sour cream coffee cake
A classic sour cream coffee cake uses 1 cup of sour cream in the batter — 16 tablespoons, or about 230 g. When you halve the recipe for a smaller tin, that becomes 8 tablespoons, or 115 g. Measuring sour cream by the spoonful for a halved recipe is slow and messy; weighing 115 g straight into the bowl is exact and quick. The weight also tells you how much moisture and fat the sour cream contributes: at 230 g per cup it is one of the wettest ingredients in the cake, which is why sour cream cakes stay moist for days and why replacing it with milk would throw the batter's balance off completely.
Topping tacos for a crowd
A taco night for ten needs about 2 tablespoons of sour cream per person, which is 20 tablespoons or roughly 288 g — a little more than one standard 230 g tub. That is a genuinely useful piece of planning arithmetic: one tub covers about eight people at a generous serving, so for ten you need a second tub or a smaller serving. Weighing also settles the question of how much is actually on each taco, which matters if anyone at the table is counting calories or fat.
How to measure a tablespoon of sour cream correctly
Sour cream is measured poured in the USDA data, which reflects how it behaves: it is thick enough to hold its shape on a spoon, but it will level itself in a measure if given a moment. The practical method is to spoon it into the tablespoon and level the top with the back of a knife, the same way you would measure cream cheese. Do not press it down or pack it — compressed sour cream weighs more and throws off the ratio. For larger amounts, weigh it directly: place the bowl on the scale, tare it, and spoon the sour cream in until you hit the target. This avoids the waste of scraping thick cream out of a measuring jug. Full-fat sour cream is the reference here; light sour cream weighs almost the same per tablespoon, but reduced-fat versions can be slightly denser because of added thickeners, so treat the 14.4 g figure as approximate for those.
When the weight matters most
Sour cream's tablespoon weight matters most when it is doing structural work in baking. In a cake or muffin batter, sour cream contributes fat, moisture and acidity in one ingredient: the fat tenderises the crumb, the moisture keeps it soft, and the acid reacts with baking soda to give lift. Change the amount by a few tablespoons and you change all three at once, which is why recipes that call for a cup of sour cream are unusually sensitive to how it is measured. In savoury cooking the weight matters differently — for sauces, where sour cream is stirred in at the end, too much thins the sauce and too little leaves it flat. And because sour cream is added off the heat to avoid curdling, there is no second chance to adjust once it is in. Knowing the weight before you start means the sauce is right the first time.
Common mistakes to avoid
The biggest mistake with sour cream is adding it to a boiling sauce, where it curdles instantly into grainy flecks. Always take the pan off the heat first, or temper the sour cream by stirring a spoonful of hot sauce into it before adding it to the pan. The second mistake is measuring it cold and packed: sour cream straight from the fridge is stiff, and a heaped tablespoon can weigh 18 g instead of 14.4 g. Let it sit for a few minutes or level it carefully. The third mistake is confusing sour cream with crème fraîche, which is richer and can be boiled without splitting, or with Greek yogurt, which is tangier and lighter per tablespoon at 15.3 g — close in weight but different in flavour and behaviour. Finally, do not freeze sour cream expecting it to come back the same; it separates and turns grainy, and while it is still fine for baking, it will never be smooth enough for a dollop again.
A note on the published figures
USDA lists sour cream at about 230 g per cup; King Arthur rounds it to 227 g. The figure used on this page — 230 g per cup, 14.4 g per tablespoon — is the USDA value, and it is the one the site's converters use, so the numbers here and the numbers in the tool always agree. If another source gives you a different figure, the difference is almost always the measuring method, not an error: a scooped cup weighs more than a spooned cup, and a packed spoonful weighs more than a level one.
Frequently asked questions
How many grams is 1 tablespoon of sour cream?
One tablespoon of sour cream weighs 14.4 g, poured, according to the USDA. One teaspoon weighs 4.8 g. These are approximate weights — brands vary slightly, so weigh it on a kitchen scale for the most accurate result.
How many tablespoons of sour cream are in 100 g?
There are about 7 tablespoons in 100 g of sour cream (100 divided by 14.4 is 6.9). A standard 230 g tub holds about 16 tablespoons, which is exactly 1 cup.
Can I use Greek yogurt instead of sour cream?
Yes, in most cases, 1:1. Greek yogurt weighs 15.3 g per tablespoon, very close to sour cream's 14.4 g, and it brings a similar tang. It works well in baking, dips and toppings, but it is leaner, so the result will be less rich, and it curdles more easily in hot sauces.
Why does sour cream curdle in hot food?
Sour cream's proteins tighten and separate when heated quickly, especially in acidic sauces. To prevent it, take the pan off the heat before stirring it in, and temper it first by mixing a spoonful of the hot sauce into the sour cream. Full-fat sour cream is more stable than light versions.
How long does sour cream last once opened?
About 1 to 2 weeks in the fridge, sealed tightly. Discard it if it smells sharply sour beyond its normal tang, tastes bitter, or shows mould. Do not freeze it for dolloping — freezing separates the texture, though it remains usable in baking.
