1 Cup Milk in Grams
1 cup of milk weighs 244 g (poured, USDA). Whole cow's milk, about 3.25% 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.
Why weighing milk beats measuring it in cups
When a recipe was written in cups and you are cooking from a metric cookbook, or the other way round, dairy is the category where a conversion table earns its keep. Milk, cream and yogurt are sold by weight in most of the world, so a recipe that says 1 cup of milk is really asking for a weighed amount on a scale. Converting once and writing the grams on the recipe card means you never have to do the maths again.
Whole cow's milk, about 3.25% fat. It is used for drinking, baking, sauces, custards and cereals. 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.
Milk cups to grams conversion table
| Cups | Grams | Tablespoons (approx.) |
|---|---|---|
| 1/4 cup | 61 g | 3.8 g |
| 1/3 cup | 81.3 g | 5.1 g |
| 1/2 cup | 122 g | 7.6 g |
| 2/3 cup | 162.7 g | 10.2 g |
| 3/4 cup | 183 g | 11.4 g |
| 1 cup | 244 g | 15.2 g |
| 1 1/2 cups | 366 g | 22.9 g |
| 2 cups | 488 g | 30.5 g |
| 3 cups | 732 g | 45.8 g |
| 4 cups | 976 g | 61 g |
The tablespoon column is a bonus for recipes that call for a spoonful or two: one tablespoon of milk weighs about 15.2 g. Remember that a cup is 16 tablespoons, so the numbers in the table are just the cup weight divided by 16, rounded to one decimal place. 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.
How the weight was measured
Poured means the ingredient is a liquid or a free-flowing syrup, so it is measured in a liquid measuring jug with a spout, read at eye level. Liquids settle flat, so there is no packing or levelling to worry about, but a sticky liquid will cling to the jug, which is one more reason to weigh it instead.
The source for the 244 g figure is USDA, and the confidence in the value is high. 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. There is a dispute worth knowing about. USDA lists whole milk at 244 g per cup; the King Arthur chart rounds milk to 227 g (8 oz by weight). We use the USDA value. The practical advice is simple: use the value in the table above, measure the way the table describes, and your results will match the recipes this site is built around. If a recipe you are following was written with a different value, follow that recipe's value instead of ours, because consistency within one recipe matters more than which authoritative number you pick.
Worked examples
A marinade for grilled chicken
A marinade using 1 cup of milk needs 244 g. When the marinade is weighed, the acid and salt ratios stay in balance, so the chicken tenderises evenly instead of turning mushy on the outside and plain inside.
A cheesecake that needs 2 cups
A cheesecake asking for 2 cups of milk needs 488 g. Cheesecake sets by ratio, and an extra 30 g of dairy can leave the centre too soft to slice cleanly. Weighing 488 g takes a moment and removes the risk.
A pancake batter for the weekend
A pancake recipe asking for 1 cup of milk needs 244 g. Pancake batter is a ratio of liquid to flour, and if the liquid is off by a few grams the pancakes are either heavy or too thin. Weighing 244 g keeps the batter the same every weekend.
When this conversion matters most
This conversion matters most when dairy is a structural ingredient rather than a flavouring. In cheesecake, panna cotta and custards, the ratio of dairy to egg and sugar decides whether the dessert sets or stays liquid. In bread and cake batters, dairy adds both moisture and acidity, so the wrong amount changes the rise. It matters less in a soup or a sauce, where you can adjust by taste, but even there a weighed amount is a better starting point.
Common mistakes with milk
- Measuring thick dairy in a liquid jug. Sour cream, yogurt and cream cheese do not pour, so a jug leaves air pockets and an inaccurate reading. Spoon them into a dry cup or weigh them.
- Not accounting for fat content. Full-fat and low-fat versions of the same dairy product weigh slightly differently. The table uses the standard full-fat product, so low-fat versions may be a gram or two lighter per cup.
- Spooning straight from the tub with a wet spoon. A wet spoon adds water weight and thins the product. Use a clean, dry spoon when measuring.
- Forgetting to stir first. Yogurt and sour cream can separate in the tub, with liquid on top. Stir before measuring so the weight is representative.
Storage and handling
Refrigerate; use within 5 days of opening. Keeping milk 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 bag 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.
Frequently asked questions
How many grams is 1 cup of milk?
1 cup of milk weighs 244 g, measured poured according to USDA. That is the figure to use when converting a recipe from cups to grams, and it is the value the conversion table on this page is built on.
How do I measure milk without a scale?
Poured means the ingredient is a liquid or a free-flowing syrup, so it is measured in a liquid measuring jug with a spout, read at eye level. Liquids settle flat, so there is no packing or levelling to worry about, but a sticky liquid will cling to the jug, which is one more reason to weigh it instead. That gives the closest result to 244 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.
Does milk always weigh the same per cup?
No. Brand, grind, moisture and how settled the container is all shift the weight by a few grams, and for flour the swing can be 20 g or more. The 244 g figure is the standard USDA value for milk measured poured, and it is the right default, but when a recipe is precise, weigh the ingredient and trust the scale over the cup.
Why do different websites give different weights for milk?
Because they are measuring different things. USDA lists whole milk at 244 g per cup; the King Arthur chart rounds milk to 227 g (8 oz by weight). We use the USDA value. A source that scoops will always report a heavier cup than a source that spoons and levels, and both can be correct about their own method. The fix is to pick one source and one method and stick with it for the whole recipe.
How should I store milk?
Refrigerate; use within 5 days of opening. Good storage keeps the ingredient fresh and keeps its weight per cup consistent, because moisture absorbed from the air adds grams that the recipe did not ask for.
What is milk used for?
Drinking, baking, sauces, custards and cereals. Whole cow's milk, about 3.25% fat.
