Milk (whole): Grams to Cups
1 cup of milk (whole) = 244 grams
One US cup of milk (whole) weighs 244 grams. One 250 ml metric cup — the one used in the UK, Australia, New Zealand and Canada — holds 258 grams. To convert any weight, divide the grams by the figure for your cup.
Whole milk weighs 244 g per US cup (USDA FoodData Central) — a little more than water because of its dissolved sugars and proteins. King Arthur Baking rounds 1 cup to 8 oz (227 g), which is close enough for most recipes.
Why milk and water are nearly interchangeable by weight
A US cup is 236.6 ml. Water at room temperature weighs about 237 g in that space; whole milk, which is around 87% water plus lactose, protein and fat, weighs about 244 g — roughly 3% more. Skim milk, with the fat removed but the solids kept, is essentially the same at 245 g.
For baking, that 3% is well inside the tolerance of any recipe. Many bakers simply treat 1 ml of milk as 1 g. Where precision matters — custards, bread hydration — weigh it.
Plant milks and buttermilk
Unsweetened almond and oat milk weigh roughly the same as dairy milk by the cup (around 240 g). Buttermilk is 245 g per cup on USDA's figure. Evaporated milk (252 g) and sweetened condensed milk (306 g) are much denser and are not substitutes cup for cup.
Metric and imperial cups of milk
A 250 ml metric cup of whole milk weighs about 258 g, and a 284 ml imperial cup about 293 g. If a British or Australian recipe says "1 cup milk", it means the 250 ml cup — about 6% more than a US cup. For most batters that difference is small, but in custard and bread it shows.
Where the 244 g figure comes from
- USDA FoodData Central: 1 cup of “Milk, whole, 3.25% milkfat, with added vitamin D” = 244 g (FDC ID 171265)
- King Arthur Baking ingredient weight chart: Milk (fresh), 1 cup = 227 g (chart)
This site uses 244 g per US cup of milk (whole), spooned and levelled. References checked September 2026.

How to measure milk (whole) accurately
The 244 g figure assumes the spooned-and-levelled method: spoon the milk (whole) into a dry measuring cup and sweep the top flat with a straight edge. Scooping the cup through the bag compacts it and gives a heavier cup.
- 1 US cup of milk (whole) = 244 g
- 1 metric cup (250 ml) of milk (whole) = 258 g
- ¾ cup = 183 g
- ½ cup = 122 g
- ⅓ cup = 81 g
- ¼ cup = 61 g
- 1 tablespoon = 15.3 g
