Grams to cups: milk

Working the other way — a recipe in grams, and cups are what you have in the drawer:

Grams of milk Cups (approx.)
50 g 0.21 cups
100 g 0.42 cups
125 g ½ cups
200 g ⅚ cups
250 g 1.04 cups
500 g 2.08 cups

Where this number comes from

Most of our weights are the King Arthur Baking chart figure, unchanged. This one is not, and it is worth saying why: Physical density: whole milk is ~1.03 g/ml, so a cup weighs more than water, not less than King Arthur's flat 227 g.

We would rather publish the number your scale will agree with and show our reasoning than quote a familiar chart that rounds the physics away. Every value we don't depart on is locked to the chart by a test, so this list stays short and deliberate — you can read all of them on the methodology page.

Frequently Asked Questions

How many grams is 1 cup of milk?

One US cup of milk weighs 240 grams (about 8.47 ounces). Physical density: whole milk is ~1.03 g/ml, so a cup weighs more than water, not less than King Arthur's flat 227 g. We publish the reason rather than the chart figure because it is what your scale will actually read.

How many grams is a tablespoon of milk?

A tablespoon of milk is about 15 grams, since one cup holds 16 tablespoons. A teaspoon is about 5 grams.

How many cups is 250 g of milk?

250 grams of milk is about 1.04 cups (250 ÷ 240). Weighing is more reliable than measuring by cup, because how you fill the cup changes the amount.
