About Milk

Milk is a staple liquid in baking and cooking. One US cup of milk weighs about 240 grams, very close to the 236.6-gram weight of pure water in the same volume.

Whether you are scaling a recipe up, substituting an ingredient, or converting a recipe from metric to US measurements, having an accurate grams-per-cup value for milk removes the guesswork from your cooking. Bookmark this page for quick reference whenever milk appears in a recipe.

How much does a cup of milk weigh?

A standard US cup of milk weighs about 240 grams (8.47 ounces). That makes it about 2.0 times heavier than a cup of all-purpose flour, and heavier than a cup of granulated sugar (200 g). This is why a converter that uses the same factor for every ingredient will give wrong answers: milk has its own density, and recipes depend on it.

Values are reference weights for level, unpacked measures unless the ingredient is normally packed. Brand, moisture, temperature and how firmly you fill the cup can shift the result by a few percent, so for precision baking weigh milk on a kitchen scale and use the cup figure only as a guide. To understand why these numbers differ between ingredients, read our guide on why a cup of flour is not a cup of sugar, or see why weighing beats measuring cups.
