1/4 Cup Sour Cream in Grams
1/4 cup of sour cream weighs 57.5 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.
Why a quarter cup is worth weighing
A quarter cup is a small measure, and small measures are where cup errors hurt most. A 5 g mistake in a full cup of sour cream is a rounding error; the same 5 g on a quarter cup is a 17 percent swing on 57.5 g, and in a small batch that swing can change the result. Recipes that call for a quarter cup are usually small, precise or both — a mug cake, a glaze, a roux, a single-serve bake — and there is no large batch to absorb the error. Weighing 57.5 g takes five seconds and removes the problem entirely.
Poured is the method behind the number, and it matters. Sour Cream 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. Grams cut through all of that: 57.5 g of sour cream is 57.5 g whatever the brand, the humidity or the size of your measuring cup.

The tablespoon column shows how many tablespoons each amount equals: a quarter cup is 4 tablespoons, and one tablespoon of sour cream weighs about 14.4 g. A cup is 16 tablespoons, so the numbers in the table are just the cup weight divided by 16, rounded to one decimal place. For small amounts a scale that reads to the gram is far more reliable than a spoon, because a heaped tablespoon can weigh half as much again as a level one. Read the table from the 1/4-cup row outwards: every other row is a multiple of 57.5 g, so scaling a recipe up or down is simple multiplication.
How the weight was measured
Poured means the ingredient is measured the way USDA measures it: poured. For sour cream, that gives 230 g per cup, and a quarter of that is 57.5 g. The source for the figure is USDA, and the confidence in the value is high. USDA publishes a standard ingredient weight chart that recipe developers use as a reference, and this page follows it exactly rather than averaging across sources, because an average of two different measuring methods is a number that matches nobody's cup.
A note on disputed figures. USDA lists sour cream at about 230 g per cup; King Arthur rounds it to 227 g. That is why this page uses the USDA value of 230 g per cup as its single, stated source, rather than averaging across charts. An average of two different measuring methods is a number that matches nobody's cup, so we pick one method, name it, and stick to it.
Worked examples
A small batch of pancakes for two
Pancakes for two need about 1/4 cup of sour cream in the batter — 57.5 g — and the amount decides whether the batter is thick enough to hold its shape or so thin it spreads across the pan. Sour Cream is cultured cream with a tangy flavour and thick texture. Weigh 57.5 g into the bowl, whisk in the egg and flour, and let the batter rest for five minutes before cooking so the flour hydrates properly.
A small batch of scones
A half-batch of scones uses about 1/4 cup of sour cream to bring the dough together — 57.5 g — and the dough should be handled as little as possible once the liquid goes in. Sour Cream is cultured cream with a tangy flavour and thick texture. Weigh 57.5 g, pour it in, and bring the dough together with a knife rather than your hands so the butter stays cold and the scones rise tall.
A dip for a party platter
A dip for a small party platter starts with about 1/4 cup of sour cream — 57.5 g — as the base, beaten smooth before the flavourings go in. The base decides the texture: too thin and the dip slides off the crudites, too thick and it tears the bread. Weighing 57.5 g gives you a consistent starting point, and you can loosen it with a spoonful of milk if it needs it.
Temperature and curdling
Dairy splits when it hits high heat, and sour cream is no exception. Never boil a sauce after the dairy goes in, and bring fridge-cold dairy to room temperature before adding it to a hot pan. The weight does not change with temperature, but the result does — and a split sauce is a waste of 57.5 g of good dairy and the whole dish with it.
Scaling a quarter cup up and down
Once you know that 1/4 cup of sour cream is 57.5 g, the rest is arithmetic. Half a cup is 115 g, three quarters is 172.5 g, and a full cup is 230 g. Doubling a recipe that calls for 1/4 cup means weighing 115 g; halving it means 28.8 g, which is 2 tablespoons. Writing the recipe in grams at this point is worth doing: the next time you make it, you weigh 57.5 g straight into the bowl and skip the measuring cup altogether. If you are scaling a recipe for a different tin size, convert every ingredient to grams first and then multiply — scaling by volume compounds the error on every ingredient at once, while scaling by weight keeps each one exact.
Common mistakes with sour cream
- Pouring thick dairy from a jug. Thick dairy pours unevenly and traps air. Spoon it into the cup and level it, or weigh 57.5 g directly.
- Adding cold dairy to a boiling pan. Cold dairy in a hot pan can split. Warm it slightly first, and add it off the boil.
- Measuring over the bowl. Drips and splashes from levelling over the bowl add dairy you did not intend. Level over the sink.
- Guessing a quarter cup by eye. A quarter cup is small, and a guess can be off by a third. A scale reading 57.5 g takes five seconds.
Storage and handling
Refrigerate; use within 2 weeks of opening. Keeping sour cream stored properly also keeps its weight per cup stable: an ingredient that has absorbed moisture from the air weighs more per cup than a dry one, so a sealed container is not just about freshness, it is about measurement accuracy too. If a bag has been open for months in a humid kitchen, the first thing to do before a precise bake is to weigh the ingredient rather than trusting the cup. Label the container with the conversion — 1/4 cup is 57.5 g — and the next person to bake with it will thank you.
Frequently asked questions
How many grams is 1/4 cup of sour cream?
1/4 cup of sour cream weighs 57.5 g, measured poured according to USDA. That is one quarter of the full-cup weight of 230 g, and it is the figure to use when converting a recipe from cups to grams. All the figures on this page are approximate, so when a recipe really matters, verify with a kitchen scale.
How many tablespoons is 1/4 cup of sour cream?
There are 4 tablespoons in a quarter cup, whatever the ingredient. One tablespoon of sour cream weighs about 14.4 g, so 4 tablespoons come to about 57.5 g. For small amounts like this, a scale that reads to the gram is more reliable than spoons, because a heaped tablespoon can weigh half as much again as a level one.
How do I measure 1/4 cup of sour cream without a scale?
Sour Cream is measured poured, according to USDA. Poured it into a 1/4-cup measure, level the top with the back of a knife, and you will be close to 57.5 g. That is the best you can do without a scale — but be honest with yourself that it is an estimate. A basic digital kitchen scale costs less than a bag of good flour and removes the guesswork from every recipe, not just this one.
What is sour cream used for?
Dips, baking, tacos and stroganoff. Cultured cream with a tangy flavour and thick texture. A quarter cup — 57.5 g — is a common amount in small batches, glazes, sauces and test bakes, which is why this conversion comes up so often.
How should I store sour cream?
Refrigerate; use within 2 weeks of opening. Good storage keeps the ingredient fresh and keeps its weight per cup consistent, because moisture absorbed from the air adds grams that the recipe did not ask for.
Why do different charts give different weights for sour cream?
USDA lists sour cream at about 230 g per cup; King Arthur rounds it to 227 g. We use the USDA figure of 230 g per cup, measured poured, so a quarter cup is 57.5 g. If a recipe you trust uses a different figure, follow that recipe's chart for that recipe — but do not mix charts inside one recipe.
