Milk — Grams & Cups Converter
1 cup of milk (also called whole milk) weighs about 240 g. So 100 g ≈ 3/8 cup, 200 g ≈ 7/8 cup, and 300 g ≈ 1 1/4 cups. Convert any amount between grams, cups, ounces, tablespoons and millilitres with the calculator below.
💡 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.

- 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.
