Whole Milk: cups to grams
Milk is slightly denser than water because of its dissolved sugars and proteins, so a cup weighs a little more than the equivalent volume of water.

Cup standards compared
Convert cooking volumes
The charts above cover weight. If you also need to move between cups, decilitres, millilitres and spoons, this converts any volume:
1 cup (US) in every unit
A US cup is 236.6 ml, a metric cup is 250 ml and a UK tablespoon is larger than a US one — so the system your recipe was written in matters. Pick the matching unit rather than assuming.
Questions
How many grams is 1 cup of whole milk?
One US cup of whole milk weighs 245 grams. That works out to a density of about 1.04 g per mL.
How many cups is 100 g of whole milk?
100 g of whole milk is about 0.41 cups, or roughly 6.5 tablespoons.
Why can’t I convert cups to grams directly?
A cup measures volume and a gram measures weight, so the conversion depends entirely on the ingredient. A cup of whole milk is 245 g, but a cup of honey is 340 g and a cup of cocoa powder is only 84 g.
Does the cup size matter?
Yes. A US customary cup is 236.59 mL, a US legal cup is 240 mL and a metric cup is 250 mL. Using a metric cup for whole milk gives 259 g instead of 245 g — about 6 percent more.
