1 Cup Milk in Grams
1 cup of milk weighs:
240 g
US cup (240 ml)
250 g
Metric / AU cup (250 ml)
American recipes mean the 240 ml cup; Australian, British and New Zealand recipes mean the 250 ml metric cup. If the recipe does not say, the cuisine usually tells you — see the full cups to grams guide.
Milk is very slightly denser than water, so a US cup comes in at about 240 g. In practice you can treat milk and water as interchangeable on a scale — the difference across a cup is under 5 g.

Frequently asked questions
How many grams is 1 cup of milk?
1 US cup of milk is 240 g. In an Australian, UK or NZ metric cup (250 ml) it is 250 g. Weighing is more accurate than measuring by volume.
How many grams is half a cup of milk?
Half a US cup of milk is 120 g, and three-quarters of a cup is 180 g.
Is 1 cup of milk the same as 1 cup of water in grams?
Almost. Milk is about 3% denser than water because of its fat, protein and sugar content, so a cup is a few grams heavier. For any home recipe the difference is negligible.
Does skim milk weigh more than whole milk?
Marginally, yes — fat is less dense than water, so removing it makes milk very slightly heavier per cup. The difference is under 2 g and never matters in cooking.
