Milk: Cups to Grams
1 cup of milk (also called whole milk) weighs about 240 g. Half a cup is 120 g, a tablespoon about 15 g, and a full cup is 8.47 ounces on a scale.
💡 Tip: Milk is roughly 240 g per cup. Whole and skim differ by only a few grams, so you can use the same figure for either.

Milk: cups, millilitres and grams line up
Milk is about 3% denser than water, so for everyday cooking its grams, millilitres and the cup measure all line up: 1 cup ≈ 240 ml ≈ 240g. That makes it one of the easiest ingredients to convert — half a cup is about 120g, a quarter cup about 60g.
Whole, low-fat and skim differ by only a few grams per cup, so the same figure works for all of them. Unsweetened plant milks (almond, soy, oat) are also close to water and convert about the same way.

Milk against the other liquids & dairy
240 g per cup places milk in the middle of its category — lighter than egg whites (243 g) and heavier than heavy cream (238 g).
It weighs the same per cup as coconut milk (240 g), so those two swap one-for-one whether you measure by cup or by scale.
Milk conversion questions
- How many cups is 100g of milk?
- About 3/8 cup — that is 100 divided by the 240 g a cup weighs.
- How many grams is 1 cup of milk?
- 1 cup of milk is about 240g, and 2 cups is 480g. Milk is close to water in density, so its weight in grams nearly matches its volume in millilitres.
- Is 1 cup of milk 240 ml?
- Almost. A US cup is 237 ml, usually rounded to 240 ml. Because milk's density is close to 1, that is also about 240g.
- Does whole milk weigh more than skim milk?
- Only by a few grams per cup. Skim is a touch denser than whole, but the difference is small enough to use about 240g for any milk.
- How many ml is 1 cup of milk?
- About 240 ml (a US cup is 237 ml, generally rounded up).
- Do plant milks weigh the same as dairy milk?
- Roughly. Most unsweetened almond, soy and oat milks are close to water, around 240g per cup, so the dairy figure is a fair estimate.
- How many cups is 225g of milk?
- About 7/8 cup — that is 225 divided by the 240 g a cup weighs.
- How many cups is 250g of milk?
- About 1 cup — that is 250 divided by the 240 g a cup weighs.
