400 Grams of Water to Cups
1⅔ cups in a US cup — and what that looks like with a measuring spoon
400 grams of water is 1⅔ cups in a US cup. In the kitchen that is 1½ cups plus 3 tablespoons.
Grams weigh and cups fill, so the answer only exists once you say what is in the cup. A US cup of water weighs 237 g, and every figure on this page comes from that one number.
It also depends on whose cup you mean. In a 250 ml metric cup — the standard in the UK, Australia, New Zealand and Canada — 400 g of water is 1⅝ cups, because that cup holds about 5.7% more than the 236.6 ml US cup.
Round to the nearest measure in a standard cup set — 1¾ cups — and you are 15 g over, about 4% of the amount.
400 g of water in each cup standard
| Cup standard | Size | Grams per cup | Cups |
|---|---|---|---|
| US customary | 236.6 ml | 237 g | 1⅔ |
| Metric (UK, AU, NZ, CA) | 250 ml | 250 g | 1⅝ |
| Imperial (older UK) | 284 ml | 285 g | 1⅜ |
A recipe that says "cups" without saying which one is almost always American. If it came from a British, Australian or New Zealand source, use the metric row.
How to measure 400 g of water without scales
Water is the one ingredient where grams and millilitres are interchangeable: 1 g of water is 1 ml. Measure it in a liquid jug at eye level rather than a dry cup.
Because 1 g of water is 1 ml, a US cup of water is 237 g and a 250 ml metric cup is 250 g. Milk, stock and juice are close but a little heavier.
- Build it as 1½ cups plus 3 tablespoons rather than guessing at 1⅔ of a cup.
- 400 g is 27 tablespoons of water, at 14.81 g per tablespoon.
- As a liquid measure that is about 399 ml — read a jug at eye level, not from above.

Frequently asked questions
How many cups is 400 grams of water?
400 grams of water is 1⅔ cups in a US cup, based on 237 g per cup. A 250 ml metric cup gives 1⅝ cups.
What is the easiest way to measure 400 g of water?
1½ cups plus 3 tablespoons — built from a standard cup and spoon set. Water is the one ingredient where grams and millilitres are interchangeable: 1 g of water is 1 ml. Measure it in a liquid jug at eye level rather than a dry cup.
Is 400 g of water the same in cups in the UK?
No. A UK, Australian, New Zealand or Canadian metric cup is 250 ml against the US cup's 236.6 ml, so 400 g of water is 1⅝ cups there and 1⅔ cups in the US.
Can I just use 1¾ cups instead?
1¾ cups of water weighs about 415 g, so you would be 15 g over. For a sauce or a soup that is fine; for a cake, where the flour-to-liquid ratio sets the crumb, weigh it.
How many ounces is 400 grams?
400 grams is 14.11 ounces by weight. Unlike cups, that answer is the same whatever you are measuring — ounces weigh, fluid ounces fill, and they are not the same unit.
