280 Grams to Cups: Exact Conversion
280 grams doesn't match a typical recipe round number, so the cup equivalent can look like an odd fraction. Of all-purpose flour, 280g is close to 2¼ cups. Every ingredient below is calculated from its own density, not a shared estimate.

Density: Why 280g Gives Different Cup Values
280g of flour and 280g of honey have identical mass, but flour is airy while honey is thick and heavy. That difference in density, not the weight itself, decides how much space each one takes up in a cup. A cup is a fixed volume, so a lighter ingredient needs more of it to reach the same weight, and a heavier ingredient needs less.
This is also why a single all-purpose grams to cups converter can't use one shared number for every ingredient. Each row in the table above is calculated from that ingredient's own density, sourced from USDA FoodData Central where available.
Granulated Sugar
280g ≈ 1⅜ cup
Butter
280g ≈ 1¼ cup
Honey
280g ≈ ⅞ cup
All-Purpose Flour
280g ≈ 2¼ cups
How 280g Is Converted, Step by Step
Every value on this page comes from that formula. For all-purpose flour, 125g fills one US cup, so 280g of flour divided by 125 gives 2.24 cups. Tablespoon and teaspoon figures scale from the cup result: 1 cup equals 16 tablespoons and 48 teaspoons, so multiplying the cup value by those factors gives the spoon measurements shown in the converter above.
Sifted: 115g. Scooped and packed: up to 150g. Recipes that specify sifted or packed flour will land on a different cup value even at the same 280g, since sifting and packing change how much air sits between the particles.
Cup Standards: US vs. Metric vs. Imperial
Not every "cup" holds the same volume. A US customary cup is 236.588ml, a metric cup is 250ml, and an imperial (UK) cup is 284.131ml. That difference shifts the cup count even when the gram amount and the ingredient stay the same.
280g of all-purpose flour: 2¼ US Customary cups, 2⅛ Metric cups, 1⅞ Imperial (UK) cups.

Getting an Accurate 280g Measurement
Most accurate
A kitchen scale reads 280g directly and removes scooping error entirely.
Dry ingredients
Spoon the flour into the cup, then level it off with a straight edge. Never scoop directly from the bag — that packs it down and adds extra weight.
Liquids
Pour into a liquid measuring cup and read the line at eye level, not from above.
Packed ingredients
Brown sugar and similar ingredients should be pressed firmly if a recipe calls for a packed cup.

Frequently Asked Questions
Why isn't 280 grams a clean fraction of a cup?+
Recipes are usually written in round numbers, so 280g falls between common markers. The math still works the same way: divide by the ingredient's grams-per-cup value.
What's a common amount close to 280 grams?+
300g is the nearest round figure most recipes use. See the nearby amounts below if your recipe might actually mean that instead.
How accurate is a 280 gram measurement using cups?+
Cup measurements for dry ingredients can vary by 10 to 20 percent depending on how they're scooped. For a specific amount like 280g, a kitchen scale gives a more reliable result than a measuring cup.
Does the cup size (US, metric, or imperial) change the answer for 280g?+
Yes. 280g of all-purpose flour is about 2¼ US cups, 2⅛ metric cups, or 1⅞ imperial cups, since each standard defines a different cup volume.
