320 Grams of Flour to Cups
2.56 cups in a US cup — and what that looks like with a measuring spoon
320 grams of all-purpose flour is 2.56 cups in a US cup. In the kitchen that is 2½ cups plus 1 tablespoon.
Grams weigh and cups fill, so the answer only exists once you say what is in the cup. A US cup of all-purpose flour weighs 125 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 all-purpose flour is 2⅜ 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 — 2½ cups — and you are 7 g under, about 2% of the amount.
320 g of flour in each cup standard
| Cup standard | Size | Grams per cup | Cups |
|---|---|---|---|
| US customary | 236.6 ml | 125 g | 2.56 |
| Metric (UK, AU, NZ, CA) | 250 ml | 132 g | 2⅜ |
| Imperial (older UK) | 284 ml | 150 g | 2⅛ |
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 flour without scales
Spoon the flour into the cup and sweep it level with a knife. Dragging the cup through the bag compacts it, and that cup weighs 140–150 g instead of 125 g — up to 20% more flour than the recipe wanted.
This is plain all-purpose flour. Bread flour packs slightly heavier at 130 g per cup and cake flour lighter at 100 g, so a recipe written for one is not a straight swap by volume.
- Build it as 2½ cups plus 1 tablespoon rather than guessing at 2.56 of a cup.
- 320 g is 40.96 tablespoons of all-purpose flour, at 7.81 g per tablespoon.
- A digital scale removes the question entirely, and costs less than the ingredients it saves.

Frequently asked questions
How many cups is 320 grams of flour?
320 grams of all-purpose flour is 2.56 cups in a US cup, based on 125 g per cup. A 250 ml metric cup gives 2⅜ cups.
What is the easiest way to measure 320 g of flour?
2½ cups plus 1 tablespoon — built from a standard cup and spoon set. Spoon the flour into the cup and sweep it level with a knife. Dragging the cup through the bag compacts it, and that cup weighs 140–150 g instead of 125 g — up to 20% more flour than the recipe wanted.
Is 320 g of flour 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 320 g of all-purpose flour is 2⅜ cups there and 2.56 cups in the US.
Can I just use 2½ cups instead?
2½ cups of all-purpose flour weighs about 313 g, so you would be 7 g under. 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 320 grams?
320 grams is 11.29 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.
