What a cup of whole milk weighs, and why it can differ

USDA’s weight for “1 cup” is 244 g. Next to a cup of water, which holds about 236.6 g, that is 103% of the weight of a cup of water, so it weighs about the same as the same volume of water. The same cup works out at 1 g per millilitre.

USDA lists one cup measure for whole milk (“1 cup”), so this page has no second figure to compare it with; if a recipe depends on the exact amount, weigh it.

USDA lists no teaspoon measure for this entry, so that weight is the cup weight divided by the US ratio (48 teaspoons to the cup).

USDA lists slightly different weights for the tablespoon and the teaspoon here: 3 teaspoons come to 15.2 g and 1 tablespoon is 15 g. The gap is rounding in the source figures.

If my recipe uses 250 ml metric cups, how much whole milk is that?

A 250 ml cup is about 5.7% larger than a US cup, so a metric cup of whole milk comes to about 257.8 g, going by USDA’s 244 g for a US cup of whole milk. The weights on this page are for the US cup of about 237 ml.

Is it better to weigh whole milk than to measure it by the cup?

For baking, yes. USDA lists one cup measure for whole milk (“1 cup”), so this page has no second figure to compare it with; if a recipe depends on the exact amount, weigh it. Next to water, a cup of whole milk is 103% of the weight of a cup of water, so it weighs about the same as the same volume of water, and 244 g on a scale is 244 g however the whole milk was scooped.

What weighs about the same as a cup of whole milk?

Among these converters, plain yogurt (245 g per cup) and ricotta cheese (246 g per cup) come closest to 244 g. Same volume, different ingredient: the weights are close, but the foods are not interchangeable.

Weights are USDA averages for the entry named below. Packing, sifting, brand and moisture change the weight of a real cup, so treat them as a good starting point, not a lab measurement.

USDA describes this entry as “Milk, whole, 3.25% milkfat, with added vitamin D” (FoodData Central SR Legacy 2018-04).
