1 Cup of Milk in Grams
244 g in a US cup — and what that figure assumes
1 cup of whole milk weighs 244 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 one cup of whole milk is 258 g there rather than 244 g.
1 cup of milk in each cup standard
| Cup standard | Size | Grams | Ounces |
|---|---|---|---|
| US customary | 236.6 ml | 244 g | 8.61 oz |
| Metric (UK, AU, NZ, CA) | 250 ml | 258 g | 9.09 oz |
| Imperial (older UK) | 284 ml | 293 g | 10.34 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 244 g measure the gap is 13.8 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 |

1 cup of milk in other units
| Unit | Amount |

| Grams | 244 g |
| Ounces (weight) | 8.61 oz |

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.
1 cup 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 | 1 cup weighs |
|---|---|---|
| Flour | 125 g | 125 g |
| Sugar | 200 g | 200 g |
| Butter | 227 g | 227 g |
Frequently asked questions
How many grams is 1 cup of milk?
1 cup of whole milk is 244 grams in a US cup, based on 244 g per full cup. In a 250 ml metric cup it is 258 g.
Is that weighed or measured?
Measured, then weighed on a scale. 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. A scale skips the question, which is why recipes that care about the result give grams.
How many tablespoons is 1 cup of milk?
16 tablespoons, or 48 teaspoons — 15.25 g per tablespoon for whole milk.
How many ounces is 1 cup of milk?
8.61 ounces by weight. That is not the same as fluid ounces — 1 cup is 8 US fluid ounces of space, whatever is filling it.
Why do different sites give different grams for 1 cup 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.
