320 Grams of Water to Cups
1⅓ cups in a US cup — and what that looks like with a measuring spoon
320 grams of water is 1⅓ cups in a US cup. In the kitchen that is 1¼ cups, 1 tablespoon plus 1¾ teaspoons.
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 — 320 g of water is 1¼ 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 — 1¼ cups — and you are 24 g under, about 8% of the amount.
320 g of water in each cup standard
| Cup standard | Size | Grams per cup | Cups |
|---|---|---|---|
| US customary | 236.6 ml | 237 g | 1⅓ |
| Metric (UK, AU, NZ, CA) | 250 ml | 250 g | 1¼ |
| Imperial (older UK) | 284 ml | 285 g | 1⅛ |
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 320 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 1¼ cups, 1 tablespoon plus 1¾ teaspoons rather than guessing at 1⅓ of a cup.
- 320 g is 21.6 tablespoons of water, at 14.81 g per tablespoon.
- As a liquid measure that is about 319 ml — read a jug at eye level, not from above.
