How many grams are in a cup of milk?
One US cup of milk weighs about 245 grams (8.6 ounces). Half a cup is about 122 g, and one tablespoon is about 15 g.
Whole milk weighs a little more than water because of its fat and protein content. Skim and 2% are within a gram or two of this figure.

Cups, fluid ounces and ounces by weight
A cup of milk is 8 fluid ounces by volume but about 8.6 ounces by weight, because milk is slightly denser than water. That small gap is a common source of confusion when a recipe mixes fluid ounces and ounces. At 245 g per cup, a gallon (16 cups) of milk weighs about 3,920 g, or just under 4 kg.
Whole, 2 percent, skim and buttermilk all fall within a gram or two of each other per cup, so one figure covers them. Unsweetened plant milks such as soy, oat and almond weigh close to the same, though sweetened versions are a little heavier. Use a liquid measuring cup, set it on a flat surface and read it at eye level.
Milk in bread dough and sauces
In baker's percentages, milk counts as about 87 percent water, because the rest is fat, protein and milk sugar. So a dough made with 300 g of milk has about 261 g of actual water. Milk also makes bread softer and browner, since the milk sugars caramelize.
When a recipe gives milk in grams, weigh it into the bowl on your scale. It is faster, dirties no extra measuring cup, and avoids the meniscus error that makes liquid measuring cups slightly inaccurate. Heat milk gently: at a boil it scorches and develops a skin, so warm it only until steaming for custards and white sauces.
