200 grams of milk in cups

Milk is dense enough that its grams and millilitres part ways. 200 grams is about 0.82 of a US cup, and only about 194 ml, not the 200 ml you might expect. Water lines up; milk does not.

Two hundred grams is not two hundred millilitres

For water the two match, a gram to a millilitre. Milk is heavier, 244 g to a cup, so 200 g of milk is only about 194 ml, and 200 ml of milk weighs about 206 g. A European recipe measuring milk in millilitres and an American one weighing grams are not asking for the same amount. The gap is small, 6 ml on 200, but it is real, and it grows with the quantity.

Three units, three answers

Ask for 200 g of milk in cups and you meet three near-misses. By weight it is 200 g; by volume about 194 ml; by the US cup 0.82, just over four-fifths. None is a round number, because milk's density, a shade over one, nudges every unit off the tidy figure. In practice, work from whichever unit the recipe starts with: if it says 200 ml, weigh out 206 g; if it says 200 g, pour a shade under 200 ml and stop. Weigh it and the density stops mattering. The milk master page has the cup weight and the eight-ounce rule behind it.

Reading up from 200 g, in US cups:

The same 200 grams is a full cup of sugar and just 0.59 of a cup of honey, each measured to its own density.

Questions about 200 grams of milk

Is 200 grams of milk a cup?

Not quite, 0.82 of one. A US cup of milk is 244 g, so 200 g is just over four-fifths. Half a cup is about 122 g.

How many cups is 200 grams of milk?

About 0.82 of a US cup, on the USDA's 244 g cup. Grams, millilitres and cups all land on different awkward numbers, so a scale is the simplest way in.
