Milk Grams to Cups
1 US cup of milk weighs 244 grams. This guide uses 244 grams for one US cup of fresh whole milk, from a measured density of 1.03 g/mL. Many charts list milk at 227 grams by treating it as 8 fluid ounces of water, which understates it: milk is denser than water, so a cup of milk weighs more than the 237 grams a cup of water weighs.

Divide the gram amount by 244 to calculate US cups. The practical fraction is a measuring aid, not a replacement for the exact gram weight.
| Grams | US cups | Practical reference |
|---|---|---|
| 25 g | 0.10 cups | about 1/8 cup |
| 30 g | 0.12 cups | about 1/8 cup |
| 40 g | 0.16 cups | about 1/8 cup |
| 50 g | 0.20 cups | about 1/4 cup |
| 60 g | 0.25 cups | about 1/4 cup |
| 75 g | 0.31 cups | about 1/3 cup |
| 80 g | 0.33 cups | about 1/3 cup |
| 100 g | 0.41 cups | about 1/3 cup |
| 120 g | 0.49 cups | about 1/2 cup |
| 125 g | 0.51 cups | about 1/2 cup |
| 150 g | 0.61 cups | about 2/3 cup |
| 200 g | 0.82 cups | about 3/4 cup |
| 250 g | 1.02 cups | about 1 cup |
| 300 g | 1.23 cups | about 1 1/4 cups |
| 400 g | 1.64 cups | about 1 2/3 cups |
| 500 g | 2.05 cups | about 2 cups |
Place a clear liquid measuring cup on a level surface and read the meniscus at eye level. If a recipe provides milk in grams, weighing it directly into the bowl is quick and avoids another cup.
Grams = cups × 244
One cup is 244 grams, one-half cup is about 122 grams and one-quarter cup is about 61 grams.
Common uses
- Cakes and pancakes
- Custards and sauces
- Bread dough
This page uses fresh whole milk at its measured density. Fat content and plant-based substitutes shift the figure, though less than most people expect.
| Type | Grams per US cup | What changes |
|---|---|---|
| Whole milk | 244 g | The reference on this page, density about 1.03 g/mL. |
| Skim milk | 245 g | Slightly denser than whole milk, since fat is the light part. |
| Buttermilk | 245 g | Close to skim by weight. |
| Heavy cream | 238 g | Lighter per cup than milk because of the fat. |
| Evaporated milk | 252 g | Concentrated, so heavier. |
| Almond milk | 242 g | Very close to dairy milk. |
| Oat milk | 245 g | Also close; the substitution is safe by weight. |
Counter-intuitively, skim milk weighs marginally more per cup than whole milk. Fat is less dense than water, so removing it makes the liquid heavier, not lighter.
Comparison figures are typical published US baking references. Only the whole milk value above is part of this site's sourced dataset.
Milk is close to water but not identical. Whole, low-fat and skim milk have slightly different densities. Use the original recipe weight when precision matters and treat the cup result as practical guidance.
The converter does not assume that every cup weighs 237 or 250 grams. It uses the documented value for the exact ingredient and state selected.
If a product label or recipe publisher supplies a different gram weight for one cup, follow that recipe-specific value for the closest match to the original testing.
Most conversion charts list a cup of milk at 227 grams. That figure comes from treating milk as if it were 8 fluid ounces of water and converting ounces of volume into ounces of weight. It is a convenient shortcut, and it is wrong in a way you can see: it makes milk lighter than water, when milk is denser than water.
Fresh whole milk has a measured density of about 1.03 g/mL. One US cup is 236.588 mL, which gives 244 grams. A cup of water is about 237 grams, so a cup of milk should weigh slightly more, and it does.
The difference is 17 grams per cup. In a pancake batter that is invisible. In a custard or a bread dough where hydration decides the texture, it is not.
Other converters publish 227 g or 237 g for milk; the source comparison page sets them side by side. If your recipe was written against a 227 g reference and gives you both cups and grams, follow the recipe's own gram figure. Where a recipe gives cups alone, the 244 g value here is the closer conversion.
Method and source
How this conversion was checked
This page uses 244 grams per US cup for fresh whole dairy milk, from a measured density of 1.03 g/mL. Skim milk is a little lighter and cream is heavier, so use the recipe's own gram weight when precision matters.

Cup standard: NIST US customary cup reference
How many grams are in one cup of milk?
One US cup of fresh whole milk weighs 244 grams.
How many cups is 100 grams of milk?
100 grams of fresh whole milk is 0.41 US cups.
How many grams is half a cup of milk?
Half a US cup is approximately 122 grams using the 244 gram full-cup reference.
Can the result vary by brand or method?
Yes. This is a practical baking reference; dairy products vary by fat level. Use the original recipe weight when precision is important.
Are these US cups or metric cups?
The results use a US customary cup. A metric cup is 250 milliliters and can produce a different answer.
