3/4 Cup Sour Cream in Grams
3/4 cup of sour cream weighs 172.5 g (poured, USDA). Cultured cream with a tangy flavour and thick texture. All the figures on this page are approximate conversions based on the USDA value of 230 g per cup, so when a recipe really matters, verify with a kitchen scale.
It is used for dips, baking, tacos and stroganoff. That range of uses is part of why the conversion comes up so often: the same ingredient appears in everyday cooking and in precise baking, and the two situations demand different levels of accuracy. Knowing the weight of 3/4 cup, rather than guessing from a measuring cup, keeps the result consistent no matter which recipe you are following, and it lets you scale a recipe up or down without the errors multiplying.
Why weighing 3/4 cup of sour cream beats measuring it in cups
Dairy is the ingredient that sets the moisture and the richness of a recipe, and 3/4 cup is an amount that appears in cakes, sauces, and soups all the time. Weighing it matters because dairy varies in thickness: milk pours freely, while sour cream and cream cheese are thick enough to trap air in a cup. A cup measure can be 10 g or more off, which is enough to change a cake from moist to dry or a sauce from silky to thin. Weighing removes that whole source of error, and it is faster than spooning a thick dairy into a cup and levelling it.

One tablespoon of sour cream weighs about 14.4 g, and one teaspoon about 4.8 g. Three quarters of a cup is 12 tablespoons, and it occupies about 177 ml by volume, the same as 3/4 cup of anything, because volume does not change from one ingredient to the next. Only the weight changes, and that is why the table above is organised by weight rather than volume. The table is rounded to the nearest tenth of a gram where the fraction demands it, so the numbers are approximate by design; the 3/4 cup figure of 172.5 g is the one to use when a recipe calls for 3/4 cup.
How the weight was measured
Poured is the method used for this ingredient, and it matters because the same cup can hold a different weight depending on how it was filled. Spooned and levelled means spooning the ingredient into the cup and levelling the top with a straight knife, without packing it down. Packed means pressing the ingredient firmly into the cup until it holds its shape. Poured means pouring a liquid into a measuring jug up to the line. Scooped means pushing the cup through a solid fat and levelling the top.
The source for the 230 g per cup figure is USDA, and this page follows that value exactly rather than averaging across sources, because an average of two different measuring methods is a number that matches nobody's cup.
USDA lists sour cream at about 230 g per cup; King Arthur rounds it to 227 g.
All the figures on this page are approximate conversions. When a recipe really matters, verify with a kitchen scale: weigh the ingredient directly into the bowl on a tared scale and trust that number over any cup.
Worked examples
A sour cream coffee cake
A coffee cake calling for 3/4 cup of sour cream needs 172.5 g. Sour cream makes the crumb exceptionally tender and moist, and its acidity activates baking soda for lift, so the amount has to be right. Weighing 172.5 g matters because sour cream is thick and a cup measure of it traps air pockets; a scooped cup can easily be 10 g short, leaving the cake drier than intended.
A dip for a party platter
A dip recipe that uses 3/4 cup of sour cream needs 172.5 g, mixed with herbs, garlic, and lemon. Here the weight matters less than the balance of flavours, but weighing still helps when you double the recipe for a crowd: two cups of dip need 345 g, and guessing by tubs is unreliable because tubs come in different sizes. Weighing keeps the doubled dip tasting the same as the original.
A beef stroganoff for six
A stroganoff that finishes with 3/4 cup of sour cream needs 172.5 g, stirred in off the heat at the end. Sour cream curdles if it boils, so it goes in last, and the amount decides whether the sauce is silky or thin. Weighing 172.5 g before you start cooking means the sour cream is ready to stir in the moment the pan comes off the heat.
When this conversion matters most
This conversion matters most in baking, where sour cream is a moisture and tenderness ingredient that also brings acid to activate baking soda. A coffee cake or a batch of muffins made with too little sour cream turns dry, while too much makes the crumb heavy and damp. Sour cream weighs 230 g per cup, so 3/4 cup is 172.5 g. In dips and stroganoff, the exact weight matters less, but the rule about heat still applies: never boil sour cream, or it will curdle and split, whatever the amount.
Common mistakes
The most common mistake is measuring sour cream in a cup, where its thickness traps air and under-measures by 10 g or more. Weigh 172.5 g on a scale instead. A second mistake is boiling a sauce after adding sour cream, which makes it split into grainy curds; stir it in off the heat. A third mistake is using the King Arthur rounded figure of 227 g per cup, which gives 170.2 g for 3/4 cup, about 2 g light; the USDA value of 230 g per cup is the reliable one.
If you do not have a kitchen scale, use the tablespoon as your measure: 3/4 cup is 12 level tablespoons, and counting them out is more accurate than filling a cup, because each spoonful is levelled individually. For dry ingredients, spoon the ingredient into the tablespoon and level it with a straight knife; for liquids, fill the spoon to the brim on a flat surface. It is slower than weighing, but it is far more reliable than a cup, and it will get you close enough for most recipes. For baking, though, a scale is worth buying: even a cheap one pays for itself the first time a cake comes out right.
Storage
Refrigerate; use within 2 weeks of opening. Cultured cream with a tangy flavour and thick texture. It is used for dips, baking, tacos and stroganoff. Knowing how the ingredient is stored matters for the conversion too: an ingredient that has absorbed moisture or dried out will weigh differently per cup, so store it properly and weigh it fresh for the best results.
Frequently asked questions
How many grams is 3/4 cup of sour cream?
3/4 cup of sour cream weighs 172.5 g, poured, using the USDA value of 230 g per cup. The figure is approximate, so verify with a kitchen scale when the recipe matters, especially for baking.
Can I use yogurt instead of sour cream?
Yes, in most recipes: plain yogurt weighs 245 g per cup, so 3/4 cup is 183.8 g, a little heavier than sour cream at 172.5 g. The tang is similar, though yogurt is thinner, so the result may be slightly less rich. For baking, the swap works well.
How many tablespoons is 3/4 cup of sour cream?
3/4 cup is 12 tablespoons, and one tablespoon of sour cream weighs about 14.5 g. That gives roughly 172.5 g for the full 12 tablespoons. Spoon it into the measure and level it, or weigh it directly for a better result.
Why does sour cream curdle in hot sauces?
Sour cream is a cultured dairy product, and high heat makes its proteins tighten and separate into curds. Always stir it in off the heat, or temper it by mixing a little hot sauce into the sour cream first, then adding the mixture back to the pan.
How long does sour cream keep?
Refrigerate sour cream and use it within two weeks of opening. It may separate slightly as it ages; stir it before weighing 172.5 g for a recipe, and discard it if it smells sharp or tastes bitter.
