How many grams are in 1 cup of whole milk?

One US cup of whole milk weighs approximately 244 grams. This is based on a volume of 240 ml and whole milk's density of about 1.034 g/ml.

Does the type of milk change the gram weight?

Yes, but the difference is very small. Whole milk is ~244 g/cup, 2% milk is ~244 g/cup, and skim milk is ~245 g/cup. For most recipes the difference is negligible, but this tool applies the correct density for each type.

How many grams is 1/2 cup of milk?

Half a cup of whole milk is approximately 122 grams. For 2% milk it is also about 122 grams, and for skim milk about 122–123 grams.

Is 1 cup of milk the same as 240 ml?

Yes. One US cup equals exactly 240 ml (236.588 ml to be precise, but 240 ml is the culinary standard). Milk weight then depends on its density, which differs slightly by fat content.

How many grams is 2 cups of milk?

Two US cups of whole milk weigh approximately 488 grams. For skim milk the figure is about 490 grams.

Can I use this converter for evaporated or condensed milk?

No. Evaporated milk (~1.066 g/ml) and sweetened condensed milk (~1.3 g/ml) are significantly denser than fresh milk. This converter covers fresh whole, 2%, and skim milk only.
