1 Cup Half-and-Half in Millilitres
1 cup of half-and-half is 236.6 ml and 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.
Dairy is measured two different ways — liquids are poured, soft and grated cheeses are spooned — and the method is part of the number. The volume never changes: one US cup is 236.6 ml. The weight does, and this page states the method and the source next to every figure so you know exactly what the grams mean.
Why millilitres and grams are two different answers
Volume and weight answer different questions, and dairy shows why both are needed. One US cup is 236.6 ml of space, and every dairy ingredient fills it — but the weight of that space runs from around 100 g to around 246 g. The difference is water, fat and trapped air. A cup of milk is nearly all water, so it weighs almost the same as water; a cup of grated cheese is mostly air, so it weighs far less. The table below lists both figures, and the gram column is the one to trust when a recipe is precise.
Half-and-Half cups to millilitres conversion table
| Cups | Millilitres | Grams | Tablespoons |
|---|---|---|---|
| 1/4 cup | 59.1 ml | 60.5 g | 4 tbsp |
| 1/3 cup | 78.9 ml | 80.7 g | 5.3 tbsp |
| 1/2 cup | 118.3 ml | 121 g | 8 tbsp |
| 2/3 cup | 157.7 ml | 161.3 g | 10.7 tbsp |
| 3/4 cup | 177.4 ml | 181.5 g | 12 tbsp |
| 1 cup | 236.6 ml | 242 g | 16 tbsp |
| 2 cups | 473.2 ml | 484 g | 32 tbsp |
| 3 cups | 709.8 ml | 726 g | 48 tbsp |
| 4 cups | 946.4 ml | 968 g | 64 tbsp |
The table covers the amounts recipes actually ask for, from a quarter cup up to four cups. One tablespoon of half-and-half is about 15.1 g and 14.8 ml, which is handy when a recipe calls for a spoonful rather than a cup: divide the cup weight by 16 and you have the tablespoon weight. Remember that the millilitre column never changes — 1 cup is always 236.6 ml — while the gram column depends on the USDA density of 242 g per cup, measured poured. If your recipe was written in grams, read the gram column; if it was written in cups or millilitres, read the millilitre column.
How much is 100 ml, 250 ml and 500 ml of half-and-half?
| Millilitres | Cups | Grams |
|---|---|---|
| 100 ml | 0.4 cups | 102.3 g |
| 250 ml | 1.1 cups | 255.7 g |
| 500 ml | 2.1 cups | 511.4 g |
Recipes written in metric units often call for round millilitre amounts rather than cups, so this table bridges the two. 250 ml of half-and-half is just over a cup — 1.1 cups — and weighs 255.7 g, while 500 ml is 2.1 cups and 511.4 g. A standard measuring jug usually has both millilitre and cup markings, so you can pour to either scale, but the gram column is the one to use on a scale. Note that 100 ml is 0.4 of a cup, which is why metric recipes rarely line up neatly with cup measures.
Worked examples
Coffee calling for 2 cups of half-and-half
A coffee recipe that calls for 2 cups of half-and-half needs 473.2 ml, which weighs 484 g. That is the figure to measure: pour 473.2 ml into a liquid jug, or weigh 484 g straight into the bowl. Because half-and-half is used for coffee, sauces and soups where cream would be too rich. the amount matters — too little and the result is flat or bland, too much and the balance of the dish tips. Weighing 484 g removes the guesswork entirely, and it is the only way to repeat the recipe exactly next time.
Sauces calling for half a cup of half-and-half
A sauces recipe that calls for half a cup of half-and-half needs 118.3 ml, which weighs 121 g. That is the figure to measure: pour 118.3 ml into a liquid jug, or weigh 121 g straight into the bowl. Because half-and-half is used for coffee, sauces and soups where cream would be too rich. the amount matters — too little and the result is flat or bland, too much and the balance of the dish tips. Weighing 121 g removes the guesswork entirely, and it is the only way to repeat the recipe exactly next time.
Soups where cream would be too rich calling for 3 cups of half-and-half
A soups where cream would be too rich recipe that calls for 3 cups of half-and-half needs 709.8 ml, which weighs 726 g. That is the figure to measure: pour 709.8 ml into a liquid jug, or weigh 726 g straight into the bowl. Because half-and-half is used for coffee, sauces and soups where cream would be too rich. the amount matters — too little and the result is flat or bland, too much and the balance of the dish tips. Weighing 726 g removes the guesswork entirely, and it is the only way to repeat the recipe exactly next time.
Scaling works the same way in both directions. Double the recipe and 3 cups becomes 1419.6 ml, or 1452 g. Halve it and you need 354.9 ml, or 363 g. When you scale, always scale by weight if the original recipe was written in grams, and by volume if it was written in cups — mixing the two mid-recipe is how scaling errors creep in. And remember that a US cup is 236.6 ml, while a metric cup is 250 ml: if you are following a recipe from Australia, New Zealand or South Africa, one cup means 250 ml, which is 255.7 g of half-and-half, not 242 g. Check which cup your recipe uses before you convert.
How the weight was measured
Poured means the ingredient is poured into a liquid measuring jug and read at eye level at the meniscus, or weighed straight into the bowl on a scale. Liquids settle flat, so a poured cup is far more repeatable than a cup of any dry ingredient.
The source for the 242 g figure is USDA, and the confidence in the value is medium. 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.
The figure is not disputed in the same way as the flour and sugar conversions: USDA lists 242 g per cup, and other reliable sources cluster close to it. Small differences of a gram or two between sources are rounding, not disagreement.
Common mistakes with half-and-half
- Measuring a thick dairy in a liquid jug. Thick cultured dairy clings to a jug and the reading is unreliable. Spoon it into a dry cup and level it, or weigh it straight into the bowl.
- Packing grated cheese down. Grated cheese should be spooned lightly and levelled. Pressing it down packs far more cheese into the cup than the recipe expects.
- Reading a liquid jug from above. A jug read from above looks fuller than it is. Read the meniscus at eye level on a flat surface.
- Using a cup for a small amount. A tablespoon or two of dairy is better weighed than measured in a cup: a small error in a cup is a large error in a spoonful.
Storage and handling
Refrigerate; use within 1 week of opening. Equal parts whole milk and light cream, about 10-12% fat. Keeping half-and-half 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 container 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. half-and-half is used for coffee, sauces and soups where cream would be too rich. and it is worth keeping a note of the 242 g per cup figure on the container, so the conversion is always to hand.
Frequently asked questions
How many cups is 250 ml of half-and-half?
250 ml of half-and-half is 1.1 cups, and it weighs 255.7 g. The table above lists 100 ml, 250 ml and 500 ml alongside their cup equivalents, so a recipe written in millilitres converts in one step. For anything more precise, weigh the half-and-half on a kitchen scale.
How many millilitres is 1 cup of half-and-half?
1 cup of half-and-half is 236.6 ml. That is the fixed volume of one US customary cup, and it is the same for every ingredient on this site: the cup does not change, only the weight inside it does. If your recipe is from a metric country, note that a metric cup is 250 ml, which is a different measure — check which cup the recipe means before converting.
How many grams is 1 cup of half-and-half?
1 cup of half-and-half weighs 242 g, measured poured according to USDA. That is the figure the conversion table on this page is built on, and it is the value to use when a recipe gives weights. All the gram figures here are approximate, so when a bake really matters, verify with a kitchen scale.
Is 1 cup of half-and-half always 236.6 ml?
Yes, as long as the recipe means a US customary cup. One US cup is 236.6 ml by definition, whatever is in it. The confusion comes from the metric cup, which is 250 ml, and from the old imperial cup. If a recipe does not say which cup it uses, a US recipe almost always means the 236.6 ml cup, while a recipe from Australia or New Zealand usually means the 250 ml metric cup.
How do I measure half-and-half without a scale?
Poured means the ingredient is poured into a liquid measuring jug and read at eye level at the meniscus, or weighed straight into the bowl on a scale. Liquids settle flat, so a poured cup is far more repeatable than a cup of any dry ingredient. That gives the closest result to 242 g per cup, but it is still an estimate: the honest answer is that a scale is the only way to know the exact weight, and a basic digital kitchen scale costs less than a bag of good flour.
