A 1 quart carton of heavy cream holds about 4 cups. A quart is 946 ml and a cup is 236.6 ml, so the division gives 4 cups exactly — the carton is designed around it. Four cups is a generous amount for the recipes that use cream: it covers a pasta sauce, a batch of whipped cream and a ganache with a cup to spare, which is why a quart is the size most cooks buy.
How many cups in a 1 quart carton?
A 1 quart carton of heavy cream holds about 4 cups (946 ml ÷ 236.6 ml per cup).
| Amount | Cups | Millilitres | Tablespoons | Grams (approx.) |
|---|---|---|---|---|
| Full 1 quart carton | 4 | 946 | 64 | 951.6 |
| Half 1 quart carton | 2 | 473 | 32 | 475.8 |
| Quarter 1 quart carton | 1 | 236.5 | 16 | 237.9 |
| 1 tablespoon | 0.06 | 14.8 | 1 | 14.89 |
The table gives the full package, half a package and a quarter of a package, plus a single tablespoon, so you can scale the answer to whatever your recipe asks for. If your packet is a different size from the one on this page, the same per-cup figure still applies — divide your packet's weight by the grams per cup, or its volume by 236.6 ml per cup, and you have your answer.
Worked examples
Whipped cream that needs two cups
A bowl of whipped cream for a cake takes 2 cups of heavy cream — half the carton — whipped with 2 tablespoons of sugar and a teaspoon of vanilla. Chill the bowl and the whisk first: cold cream whips in minutes, warm cream takes twice as long and can turn to butter before it peaks. Two cups of cream whips up to about 4 cups of whipped cream, since whipping roughly doubles the volume. Stop at soft peaks for a cake filling and firm peaks for piping.
Alfredo sauce that needs one and a half cups
A pan of Alfredo sauce for four takes about 1 and a half cups of heavy cream — 355 ml — simmered with 1/2 cup of butter and 1 cup of grated parmesan. The cream must simmer gently, never boil hard, or it separates. A cup and a half is just over a third of the carton, so one quart covers two pans of Alfredo with a cup left over. Add the cheese off the heat or it goes grainy.
Chocolate ganache that needs one cup
A ganache for a cake takes 1 cup of heavy cream — a quarter of the carton — heated until it steams and poured over 8 oz of chopped chocolate. Let it sit for two minutes before stirring, and it turns glossy and smooth. One cup is the standard ratio for a pouring ganache; for a thicker truffle ganache, use half a cup of cream to the same chocolate. The remaining three cups in the carton cover the whipped cream for the top.
How the figure was measured
The weight figures on this page come from USDA: heavy cream weighs about 238 g per cup, measured poured, and that figure carries high confidence in CookScale's 120-ingredient table. But the cup figures themselves do not depend on weight at all — a cup is 236.6 ml whether it holds oil, milk, cream or soy sauce — so the headline answer is exact arithmetic, not an estimate. The gram figures are the approximate ones, because they depend on density, and they should be verified with a kitchen scale when a recipe gives grams and the amount matters. Package sizes vary by brand and region, so check the volume printed on your own bottle or carton before planning around this page.
There is a dispute note on this figure: the King Arthur chart rounds heavy cream to 227 g per cup, while the USDA lists it at about 238 g per cup. CookScale uses the USDA value.
How to measure it
Dairy is measured by volume in most recipes and by weight in most professional ones, and the two agree closely enough that either works — as long as you use the right figure. Milk, cream and cottage cheese pour, so use a liquid jug and read it at eye level; cream cheese and ricotta are spooned, so press them into a dry cup measure and level the top, checking for air pockets. Do not pack cream cheese the way you would brown sugar — firm pressure is enough, and over-packing is how a cheesecake ends up dense. For anything where the amount matters (a custard, a cheesecake, a sauce that must set), weigh it: the gram figures on this page come from USDA or King Arthur tables, and a scale removes the guesswork entirely.
Practical guidance
Dairy is the ingredient most likely to be measured from a carton that has already been opened, which is why the "how much is left" question matters. Write the opening date on the carton and keep it at the back of the fridge, where the temperature is steadiest — the door is the warmest spot and shortens its life. Never pour unused milk or cream back into the carton after it has sat in a jug on the counter; bacteria from the jug travel with it. If a recipe needs a cup and you have half a cup left, do not top it up with water in a custard or a sauce — the fat and protein are doing real work, and water dilutes both. Sour cream and cottage cheese past their date are not a measuring problem; they are a bin problem.
Four cups is the number to plan around, and it helps to think of the carton in quarters: a quarter is a ganache, half is a bowl of whipped cream, three-quarters is a large sauce. If your recipe needs only a cup and you have a quart open, plan a second cream recipe within the week — a soup, a pasta sauce, a batch of scones — rather than letting three cups go to waste. Check whether your carton is a quart or a pint before you start: pints hold 2 cups, and a recipe written for a quart will leave you short. And buy the smallest carton that covers your recipe if you rarely use cream, because an opened carton does not keep.
Frequently asked questions
How many cups are in a quart of heavy cream?
There are 4 cups in a quart of heavy cream. A US quart is 946 ml and a US cup is 236.6 ml, so 946 divided by 236.6 gives 4 cups exactly. In pints that is 2 pints, and in fluid ounces 32 fl oz. The figure is exact for volume, and it is the same for any liquid sold by the quart.
How many grams are in a quart of heavy cream?
A quart of heavy cream weighs about 952 g. Heavy cream weighs about 238 g per cup according to the USDA, so 4 cups is about 952 g. The King Arthur chart rounds cream to 227 g per cup, but the USDA figure of 238 g is the more accurate one. For recipes given in grams, use 238 g per cup.
How many cups are in a pint of heavy cream?
There are 2 cups in a pint of heavy cream. A pint is 473 ml, which divides by 236.6 ml to give 2 cups. Pints are the size many recipes assume for a single use — a pint covers a bowl of whipped cream with nothing left over, while a quart covers the whipped cream and a sauce.
Can I substitute milk for heavy cream cup-for-cup?
Not in recipes that depend on cream's fat. Milk has about 3.5 percent fat against cream's 36 percent, so a sauce made with milk will be thin and can curdle, and milk will not whip. For a soup or a sauce where richness matters less, use 3/4 cup of milk plus 1/4 cup of melted butter for every cup of cream. For whipping, there is no substitute except another cream.
How long does an opened carton of heavy cream last?
An opened carton of heavy cream lasts about five to seven days in the fridge, and ultra-pasteurised cream lasts longer — check the date on the carton. Keep it at the back of the fridge, not in the door, and never pour unused cream back into the carton. If it smells sour or has thickened into lumps, discard it; soured cream is not safe for a sauce the way soured milk can be in baking.
