Cups of Milk to grams
One US cup (240 ml) of whole milk weighs about 244 grams (8.6 oz), measured liquid measure.
Milk is one of the easy ones: it is a liquid, so a cup of it always weighs essentially the same. Whole milk is slightly denser than water, which is why a 240 ml cup weighs 244 g rather than 240 g.

|---|---|---|---|---|
| ⅛ | 31 g | 30 g | 32 g | 36 g |
| ¼ | 61 g | 60 g | 64 g | 72 g |
| ⅓ | 81 g | 80 g | 85 g | 96 g |
| ½ | 122 g | 120 g | 127 g | 144 g |
| ⅔ | 163 g | 160 g | 169 g | 193 g |
| ¾ | 183 g | 180 g | 191 g | 217 g |
| 1 | 244 g | 241 g | 254 g | 289 g |

How to measure Milk by volume
- Use a clear liquid measuring cup on a level surface.
- Fill to the line and check at eye level — looking down at the cup misreads the meniscus.
- Any drinking milk (whole, semi-skimmed, skimmed) is close enough to swap gram-for-gram.
Why the weight varies
Whole milk is slightly denser than water. Skimmed and plant-based milks differ a little, and temperature has a small effect.
Because liquids do not compress, converting milk is exact in a way flour never is. The only real trap is confusing fluid ounces (volume) with weight ounces: a cup of milk is 8 fl oz but 8.6 oz by weight.
Which value we publish, and why
We publish 244 g per US cup, the USDA FoodData Central figure for whole milk (3.25% fat). King Arthur’s chart rounds a cup of milk to 227 g (8 oz).
