3/4 Cup Half-and-Half in Grams
3/4 cup of half-and-half weighs 181.5 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 of 242 g per cup, so when a recipe really matters, verify with a kitchen scale.
It is used for coffee, sauces and soups where cream would be too rich. 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.
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 242 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.
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.

One tablespoon of half-and-half weighs about 15.1 g, and one teaspoon about 5 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 181.5 g is the one to use when a recipe calls for 3/4 cup.
When this conversion matters most
This conversion matters most in soups, sauces, and quiche, where half-and-half is the dairy that sets the richness without the weight of cream. A soup with too much half-and-half tastes flat and heavy; a quiche with too little will not set properly. Half-and-half weighs 242 g per cup, so 3/4 cup is 181.5 g, almost the same as milk at 183 g, which means the two are close by weight but very different in fat. In coffee, the exact weight is irrelevant and a splash is the only measure you need. One practical point: half-and-half curdles more easily than cream in acidic sauces, so add it gently and keep the heat low.
Worked examples
A creamy mushroom soup for six
A soup recipe calling for 3/4 cup of half-and-half needs 181.5 g, stirred in at the end off the heat. Half-and-half enriches the soup without making it as heavy as cream, and the amount decides whether the soup is silky or thin. Weighing 181.5 g matters because the soup is a ratio: too much half-and-half drowns the mushroom flavour, too little leaves the soup watery.
A coffee cake with a tender crumb
A coffee cake that uses 3/4 cup of half-and-half needs 181.5 g. Half-and-half adds richness to a cake batter without the weight of cream, and its fat keeps the crumb tender for days. Weighing the half-and-half is more accurate than a jug measure, because the difference between a moist cake and a dry one is only about 20 g of liquid either way.
A quiche filling, doubled for a brunch
Doubling a quiche recipe that calls for 3/4 cup of half-and-half means 1 1/2 cups, or 363 g. The custard ratio of eggs to dairy decides whether the quiche sets firm or stays wobbly, so the dairy weight has to be right. Weighing 363 g for the doubled filling keeps both quiches setting the same way, instead of one firm and one runny.
Common mistakes
The most common mistake is swapping half-and-half for cream gram-for-gram in a recipe that needs cream to whip or to enrich a sauce. Half-and-half will not whip, and it is thinner, so the result will be different even though the weight is close. A second mistake is boiling a sauce after adding half-and-half, which can make it curdle; stir it in at the end off the heat. A third mistake is reading a jug at the wrong angle; weigh 181.5 g on a scale instead.
If you do not have a kitchen scale, measure with tablespoons instead of a cup: 3/4 cup is 12 level tablespoons, and levelling each spoonful separately keeps the total far closer to the true weight than a single cup measure. For thick ingredients like sour cream or cream cheese, press the spoonful in firmly and level the top; for liquids, fill the spoon on a flat surface. This method works well for cooking, where a few grams either way do not matter, but for baking, a scale is the better investment: it removes the guesswork entirely and makes every recipe repeatable.
Why weighing 3/4 cup of half-and-half 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.
Storage
Refrigerate; use within 1 week of opening. Equal parts whole milk and light cream, about 10-12% fat. It is used for coffee, sauces and soups where cream would be too rich. 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 half-and-half?
3/4 cup of half-and-half weighs 181.5 g, poured, using the USDA value of 242 g per cup. The figure is approximate, so verify with a kitchen scale when the recipe matters, especially for quiche and sauces.
Can I use milk instead of half-and-half?
You can in a pinch, but the result will be thinner and less rich: milk weighs 244 g per cup, so 3/4 cup is 183 g, almost the same weight, but milk has far less fat. For a sauce, add a knob of butter with the milk to make up some of the richness.
How many tablespoons is 3/4 cup of half-and-half?
3/4 cup is 12 tablespoons, and one tablespoon of half-and-half weighs about 15 g. That gives roughly 181.5 g for the full 12 tablespoons. Weighing the half-and-half into a jug on the scale is the most accurate method.
Will half-and-half whip like cream?
No. Half-and-half is only 10 to 12 percent fat, while cream needs at least 36 percent fat to whip. No amount of whisking will make half-and-half hold peaks, so use heavy cream at 178.5 g per 3/4 cup for whipping.
Why does half-and-half curdle in tomato sauce?
Half-and-half has less fat than cream to protect its proteins, so acid and high heat make it curdle. Add it at the end off the heat, warm it gently, and stir it in slowly. If the sauce is very acidic, use cream instead, which is more stable.
