Milk: Cups to Grams
Quick answer: One US cup of milk weighs about 245 grams (8.6 oz), and one tablespoon about 15 g.
US recipes measure milk in cups; the rest of the world weighs it. Convert any amount in either direction — and measure it the way the chart assumes: use a liquid measuring cup on a level surface and read at eye level.

| ⅔ cup | 163 g | 5.8 oz |
| ¾ cup | 184 g | 6.5 oz |
| 1 cup | 245 g | 8.6 oz |
| 1½ cups | 368 g | 13 oz |

How it works
Cups measure volume and grams measure weight, so the conversion runs through density: milk packs about 245 g into a US cup (237 ml). Volume is only as accurate as your technique — use a liquid measuring cup on a level surface and read at eye level. That variability is exactly why serious baking recipes list grams, and why a $15 kitchen scale upgrades every bake. If your recipe uses metric cups (250 ml), the weights run about 5% higher.
Frequently asked
How many grams are in a cup of milk?
About 245 grams (8.6 oz) per US cup, measured properly. A tablespoon is about 15 g.
How many cups is 250 g of milk?
About 1.02 cups. Divide any gram amount by 245 to get cups — or flip the converter above to grams and it does it for you.
Is a cup of milk the same as a cup of water?
Nearly — milk is about 3% denser (245 g vs 237 g per cup). For cooking they're interchangeable by volume; for precise baking formulas, weigh.
