1 Cup Half-and-Half in Grams
1 cup of half-and-half weighs 242 g (poured, USDA). Equal parts whole milk and light cream, about 10-12% fat. All the figures on this page are approximate conversions based on the USDA value, so when a recipe really matters, verify with a kitchen scale.
Half-and-half is equal parts whole milk and light cream, about 10 to 12 percent fat, and it is the dairy that sits between milk and cream in richness. A cup weighs 242 g, poured, just a little less than milk at 244 g, and it is used in coffee, sauces and soups where cream would be too rich and milk would be too thin. It pours like milk and enriches like cream, which makes it the default dairy for coffee in the United States, where it is sold in small cartons beside the milk. Its one weakness is that it can curdle in very acidic or very hot dishes, because it does not have enough fat to protect it the way heavy cream does.
Why weighing half-and-half beats measuring it in cups
Dairy ingredients are measured in cups more than almost anything else, because milk, cream and yogurt pour easily and recipes were written that way for generations. But the weight per cup varies more than most cooks expect: a cup of milk weighs 244 g, a cup of heavy cream 238 g, a cup of sour cream 230 g, and a cup of grated parmesan only 100 g. The reason is composition: water, fat, protein and air all pack differently, and grated or curdled dairy traps air in a way that liquid dairy does not. In baking, dairy adds moisture, richness, acidity and browning, and the amount matters: too much liquid dairy makes a batter slack, too little makes it dry. Weighing dairy is quick, because it pours straight onto the scale, and it removes the meniscus reading error that comes with every jug.

One tablespoon of half-and-half weighs about 15.1 g, and a cup is 16 tablespoons, so the tablespoon column is simply the cup weight divided by 16. 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. All the values in this table are approximate, and they assume the ingredient is measured poured, exactly as the source measured it.
How the weight was measured
The figure on this page comes from USDA, measured poured unless the method line says otherwise. Spooning means filling the cup with a spoon rather than plunging the cup into the bag, and levelling means sweeping a knife across the rim. Scooping packs the ingredient down and can add a fifth or more to the weight, which is why two bakers following the same cup-based recipe can get visibly different results. Confidence in this value is medium. That reflects how consistent the ingredient is from brand to brand: a uniform, factory-packed ingredient is more predictable than a fresh, variable one. Even a high-confidence figure is still an approximation, because moisture, grind size and settling all shift the weight a little. Treat the grams on this page as a reliable starting point and check with a scale when the recipe is fussy, expensive, or being made for the first time.
Worked examples
Coffee for the morning
A cup of coffee that takes 1/4 cup of half-and-half needs 60.5 g, poured in and stirred. The half-and-half lightens the coffee and adds richness without the heaviness of cream, and because it is only about 10 percent fat, it does not leave the greasy film that cream can leave on a hot drink. Weighing it is unnecessary for a single cup, but for a large pot of coffee for a crowd, a cup weighs 242 g and measuring by weight keeps the strength consistent.
A creamy soup
A soup that calls for 1 cup of half-and-half needs 242 g, stirred in at the very end of cooking, off the heat. The half-and-half enriches the soup and gives it a silky texture, but if it is boiled it can curdle, so add it last and warm it through gently. If the soup is very acidic, such as a tomato soup, temper the half-and-half first by whisking a little hot soup into it before adding it to the pot.
A pan sauce
A pan sauce that uses 1/2 cup of half-and-half needs 121 g, poured into the pan after the meat has been removed and the pan has been deglazed. The half-and-half picks up the browned bits from the bottom of the pan and turns them into a smooth, creamy sauce in a minute or two. Reduce it gently rather than boiling it hard, and season it at the end, because the sauce will thicken as it cools and salt added early can make it too salty.
When this conversion matters most
This conversion matters most in baking and sauces, where dairy is part of the liquid balance of the recipe. A cake batter with too much milk is slack and sinks; a sauce with too little cream will not coat the pasta. It matters less in cooking where dairy is added to taste, such as a splash of cream in a soup or milk in mashed potatoes, because you can adjust as you go. It matters again with cheese, because grated cheese is mostly air by volume and its weight per cup depends on how finely it is grated and how hard it is pressed, so a recipe that says two cups of cheese can mean anything from 200 g to 300 g. Weighing cheese is the only way to know which one the recipe meant.
Common mistakes
The most common mistake is reading a liquid jug from above instead of at eye level, which can add or subtract a tablespoon without you noticing. The second is measuring grated cheese by pressing it down into the cup: grated cheese should be spooned in lightly and levelled, because packing it can add 20 g or more per cup. The third is using a dry cup for liquids, which has no pouring spout and no level line, so you end up guessing. And the fourth is forgetting that dairy separates: cream rises, yogurt weeps whey, and ricotta drains, so stir or drain the ingredient before measuring, and measure the state the recipe expects.
What to do if you do not have a scale
If you do not have a scale, use a liquid measuring jug for anything that pours, and set it on a flat surface and read it at eye level, using the bottom of the meniscus as the line. For spoonable dairy such as yogurt, sour cream, ricotta and cottage cheese, use a dry cup, spoon the ingredient in, and level it with a knife, exactly as you would flour. For grated cheese, spoon it in lightly and do not press it down. These methods work well for dairy, because liquids are the most consistent ingredients by volume, but for baking, where dairy is part of the liquid ratio, weighing is still the more reliable route.
Storing half-and-half
Refrigerate; use within 1 week of opening. Keeping half-and-half properly stored matters for the conversion as well as for the flavour: an ingredient that has absorbed moisture from the air weighs more per cup than a dry one, and one that has dried out weighs less. Store it in an airtight container, away from heat and light, and measure it in the state the recipe expects, not straight from a damp or stale bag.
Frequently asked questions
What is the difference between half-and-half and cream?
Half-and-half is equal parts milk and cream and is about 10 to 12 percent fat, while heavy cream is at least 36 percent fat. A cup of half-and-half weighs 242 g, while a cup of heavy cream weighs 238 g, so they are close by weight but very different in richness. Half-and-half will not whip, and it can curdle in acidic dishes, while heavy cream whips to firm peaks and is stable in hot, acidic sauces. Use half-and-half for coffee and for light enrichment, and cream when the recipe needs body and stability.
Can I make half-and-half at home?
Yes. Half-and-half is, by definition, equal parts whole milk and light cream, so mix half a cup of milk with half a cup of light cream and you have a cup of half-and-half. The homemade version will taste the same and behave the same in coffee and in cooking, and it is a useful fix when the shops are closed.
Can I use cups instead of a scale for half-and-half?
Yes, but a scale is more accurate. If you measure half-and-half poured, exactly as the figure on this page was measured, a cup will be close to 242 g, within a few grams. The problem is that most people scoop rather than spoon, which can add 15 to 25 percent to the weight, and that error is enough to change a bake. For everyday cooking, cups are fine. For baking, where the ratio of ingredients decides the result, weigh it and check the number on the scale.
How many tablespoons are in a cup of half-and-half?
There are 16 tablespoons in a US cup, so a cup of half-and-half is 16 tablespoons, and one tablespoon weighs about 15.1 g. A teaspoon weighs about 5 g. Tablespoons are useful when a recipe calls for a small amount, but they carry the same packing problem as cups: a heaped tablespoon can weigh half as much again as a level one, so level every spoon with the back of a knife, and use a scale for small amounts when accuracy matters.
Does the weight change if I pack or sift half-and-half?
Packing does not apply to half-and-half, because it is poured rather than spooned. The weight is consistent as long as the liquid is measured at eye level in a jug and the ingredient is stirred first if it separates. Temperature makes a small difference, because warm liquids expand slightly, but for ordinary kitchen use the poured weight is stable, and a cup of half-and-half weighs about 242 g whether it is cool or at room temperature.
