3 Cups of Milk in Grams
732 g in a US cup — and what that figure assumes
3 cups of whole milk weighs 732 grams, measured in a US cup.
That figure comes from one number: a full US cup of whole milk is 244 g. Everything else on this page is that number scaled.
Pour milk into a liquid measuring jug and read it at eye level. A dry measuring cup filled to the brim is hard to carry without spilling.
Whose cup you mean changes the answer. A 250 ml metric cup — the standard in the UK, Australia, New Zealand and Canada — is 5.7% larger than the 236.6 ml US cup, so three cups of whole milk is 773 g there rather than 732 g.
3 cups of milk in each cup standard
| Cup standard | Size | Grams | Ounces |
|---|---|---|---|
| US customary | 236.6 ml | 732 g | 25.82 oz |
| Metric (UK, AU, NZ, CA) | 250 ml | 773 g | 27.28 oz |
| Imperial (older UK) | 284 ml | 879 g | 31.01 oz |
A recipe that just says "cups" is almost always American. If yours came from a British, Australian or New Zealand source, take the metric row — on a 732 g measure the gap is 41.5 g.
Halving and doubling milk
Recipes get scaled more often than they get followed exactly. These are the portions of whole milk a cook actually reaches for, already weighed out.
| Cups | Grams | Ounces | Tablespoons |
|---|---|---|---|
| ¼ cup | 61 g | 2.15 oz | 4 |
| ⅓ cup | 81.3 g | 2.87 oz | 5.33 |
| ½ cup | 122 g | 4.30 oz | 8 |
| ⅔ cup | 163 g | 5.74 oz | 10.67 |
| ¾ cup | 183 g | 6.46 oz | 12 |
| 1 cup | 244 g | 8.61 oz | 16 |
| 1½ cups | 366 g | 12.91 oz | 24 |
| 2 cups | 488 g | 17.21 oz | 32 |
| 3 cups | 732 g | 25.82 oz | 48 |

Whole milk is 244 g per US cup — slightly heavier than water because of the milk solids. Skim milk is 245 g and most plant milks are about 240 g, so the difference rarely matters in a recipe.
3 cups of something else
The same cup holds a different weight of everything, because ingredients do not weigh the same for their size.
| Ingredient | Grams per US cup | 3 cups weighs |
|---|---|---|
| Flour | 125 g | 375 g |
| Sugar | 200 g | 600 g |
| Butter | 227 g | 681 g |
| Rice | 185 g | 555 g |
| Oats | 90 g | 270 g |

Why do different sites give different grams for 3 cups of milk?
Because a cup is a volume and the weight depends on how it was filled, and on whose cup. This site uses 244 g per US cup. Whole milk is 244 g per US cup — slightly heavier than water because of the milk solids. Skim milk is 245 g and most plant milks are about 240 g, so the difference rarely matters in a recipe.
