There are about 4.2 cups in a kilogram of heavy cream. That is the short answer, and it is the number this page is built around: one US cup of heavy cream weighs 238 g poured, according to USDA, so 1,000 g divided by 238 g gives 4.2 cups. Every figure on this page is approximate, because cup weights shift a little with how the cup is filled, and when the result matters — a cake, a brine, a batch of jam — a kitchen scale is the only way to be exact.

Heavy Cream is cream with at least 36% fat that whips to firm peaks. It is used for whipping, ganache, sauces and soups. That is why the kilogram-to-cups question comes up so often: heavy cream is sold by weight in most countries, while many recipes — especially American ones — measure it in cups. This page converts the whole kilogram, not just a single cup, so you can plan a whole bag or tub against a recipe instead of converting one spoonful at a time.

Conversion table: kilograms of heavy cream to cups

One US cup is 236.6 ml, and one cup of heavy cream weighs 238 g poured. Every row below is that cup weight divided into the weight shown, so the whole table follows from a single number. Figures are rounded to two decimal places and labelled approximate.

Weight Cups (approx.)
100 g 0.42
250 g 1.05
500 g 2.1
750 g 3.15
1 kg (1,000 g) 4.2
1.5 kg (1,500 g) 6.3
2 kg (2,000 g) 8.4

The same cup weight works in the other direction too:

Measure Weight (approx.)
1 cup 238 g
1 tablespoon 14.9 g
1 teaspoon 4.96 g
1 kg in tablespoons about 67 tbsp

If you only need part of the kilogram, the table above is the fastest way to read it off. Half a kilogram is 2.1 cups, a quarter is 1.05 cups, and 100 g — a common recipe amount — is 0.42 cups.

How the figure is worked out

The calculation is a single division: 1,000 g ÷ 238 g per cup = 4.2 cups. The only input is the weight of one cup of heavy cream, and that comes from USDA, which lists one US cup of heavy cream at 238 g, poured. The confidence rating on that figure is high, which means it is a published, checked value rather than an estimate — but it is still a cup measurement, and cups are never as exact as grams.

One thing to know before you use the number: USDA lists heavy cream at about 238 g per cup; King Arthur rounds it to 227 g.

Poured means filling the cup from a jug and reading the level at eye height, with the cup on a flat surface. Liquids do not pack or settle the way dry ingredients do, so the main error is a meniscus read at an angle or a cup that is not quite level.

That is also why every number here carries the word approximate. A cup is a volume measure being used as a stand-in for weight, and the two only line up when the filling method matches the published one. If the dish is forgiving — a stew, a marinade, a crumble topping — the cup figure is plenty. If it is a cake, a loaf of bread, or anything where a 10% error changes the texture, weigh the ingredient on a kitchen scale and skip the cups entirely.

Worked examples

The table is useful, but recipes do not come in kilograms. Here are three ordinary situations where the kilogram-to-cups figure does real work.

Example 1 — a sauce from a 1 kg tub

A pasta sauce needs 2 cups of heavy cream, which weigh 476 g. A 1 kg tub gives you 4.2 cups, so the sauce takes just under half the tub and leaves about 2.2 cups — enough for a second, smaller pan of sauce or a round of baking the next day. Check the tub's use-by date before planning the second use; dairy does not wait around.

Example 2 — pancakes for a crowd

Pancake batter for six people calls for 1 cup of heavy cream (238 g). Doubling the batter for twelve takes 2 cups, 476 g, which is still well under a kilogram. The leftover 2.2 cups can go into the next morning's batter, but do not stretch it past the date on the pack — the conversion is exact, the shelf life is not.

Example 3 — a dessert that needs weight, not cups

A cheesecake or frosting recipe may list heavy cream in grams — say 250 g. That is 1.05 cups, a little over one cup. Spooning heavy cream into a cup traps air and gives a short measure, so for desserts the gram figure on the scale is the one to trust, with the cup figure as a rough check.

Measuring it well, and storing what is left

The most common mistake with heavy cream is spooning it into a dry measuring cup. Thick dairy traps air pockets and clings to the sides, so the cup reads short by a surprising amount. Use a liquid jug for pourable dairy and a scale for thick dairy — spoon it into a bowl on the scale and read the grams directly. The second mistake is guessing at a half-used tub: a tub that looks half full is not necessarily half a kilogram, because tubs are rarely filled to the brim.

Storage matters once you have opened a kilogram pack. Refrigerate; use within 1 week of opening. A kilogram is a lot of heavy cream for a home kitchen — for most households it will last weeks or months — so decanting it into a sealed container on the day you open it is worth doing: it keeps the weight stable, keeps moisture out, and means the cup you measure in a month weighs the same as the cup you measure today.

Without a scale, tablespoons are the fallback: one kilogram of heavy cream is about 67 level tablespoons, and one cup is 16 tablespoons, so you can build any amount in the table above from spoonfuls. It is slower than weighing, and each spoonful adds its own small error, but for soups, marinades, and everyday cooking it is close enough. For baking, borrow or buy a scale — it is the single cheapest upgrade to a home baker's accuracy.

Buying it by the kilogram

Shops sell heavy cream by weight, and the kilogram is the standard pack size in most countries outside the United States. Knowing that the pack holds about 4.2 cups lets you compare it honestly against smaller packs: a 500 g pack is 2.1 cups, so if the kilogram costs less than twice the 500 g price, it is the better buy — provided you will use it before it goes stale. For heavy cream, whipping, ganache, sauces and soups. Work out how many cups your household actually uses in a month before choosing the big pack; a bargain that ends up thrown away is not a bargain. And remember the figure is approximate: if the recipe on the packet is written in grams, follow the grams. Cups are a translation, not the original.

Frequently asked questions

How many cups are in 1 kg of heavy cream?

About 4.2 cups. One cup of heavy cream weighs 238 g poured (USDA), and 1,000 g ÷ 238 g = 4.2 cups. The figure is approximate, because how firmly the cup is filled changes the weight slightly.

How many grams is 1 cup of heavy cream?

238 g, poured, according to USDA. That is the single number every conversion on this page is built from — multiply it by the number of cups for grams, or divide a gram weight by it for cups.

Is 4.2 cups per kilogram exact?

No — it is a close, practical figure. Cup weights vary with filling method, humidity, and how settled the ingredient is in the pack. For everyday cooking the error is small enough not to matter. For baking, brines, or anything where a 10% error changes the result, weigh the ingredient on a kitchen scale instead of converting.

How many cups are in 500 g of heavy cream?

About 2.1 cups — half the kilogram figure. The same division applies: 500 g ÷ 238 g per cup = 2.1 cups. The conversion table near the top of the page lists 100 g, 250 g, 750 g, 1.5 kg, and 2 kg as well.

Why do different sources give different cup weights for heavy cream?

USDA lists heavy cream at about 238 g per cup; King Arthur rounds it to 227 g. This page uses the primary published figure and states it plainly, so you can adjust if your recipe book uses a different one.
