800 Grams of Water to Cups
3⅜ cups in a US cup — and what that looks like with a measuring spoon
800 grams of water is 3⅜ cups in a US cup. In the kitchen that is 3¼ cups plus 2 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 — 800 g of water is 3¼ 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 — 3½ cups — and you are 30 g over, about 4% of the amount.
800 g of water in each cup standard
| Cup standard | Size | Grams per cup | Cups |
|---|---|---|---|
| US customary | 236.6 ml | 237 g | 3⅜ |
| Metric (UK, AU, NZ, CA) | 250 ml | 250 g | 3¼ |
| Imperial (older UK) | 284 ml | 285 g | 2.81 |
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 800 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 3¼ cups plus 2 tablespoons rather than guessing at 3⅜ of a cup.
- 800 g is 54.01 tablespoons of water, at 14.81 g per tablespoon.
- As a liquid measure that is about 799 ml — read a jug at eye level, not from above.

Frequently asked questions
How many cups is 800 grams of water?
800 grams of water is 3⅜ cups in a US cup, based on 237 g per cup. A 250 ml metric cup gives 3¼ cups.
What is the easiest way to measure 800 g of water?

Is 800 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 800 g of water is 3¼ cups there and 3⅜ cups in the US.
Can I just use 3½ cups instead?
3½ cups of water weighs about 830 g, so you would be 30 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.
