All-Purpose Flour grams to cups
One US cup of all-purpose flour weighs about 120 grams.
The default flour in most recipes, milled from a blend of hard and soft wheat to a moderate protein content that suits nearly everything. It is a fine powder full of trapped air, which is why a cup of it weighs less than half a cup of honey and why how you fill the cup matters so much.

One US cup is 16 tablespoons or 48 teaspoons, whatever is in it — those two are volume measures, so no density is involved.
How you measure it changes the weight
Most converters publish a single number. In practice the technique matters, so here is what a cup weighs depending on how it was filled.
| Method | 1 cup weighs | What that means |
|---|---|---|
| Sifted | 110 g | Sifted into the cup, then levelled without tapping or pressing. |
| Spooned & levelled default | 120 g | Spooned into the cup, then levelled with a straight edge. The method a recipe means by "1 cup all-purpose flour". |
| Dipped & scooped | 140 g | The cup dipped directly into the container, compacting the ingredient. |
Measuring notes
Stir the flour to loosen it, spoon it into the cup, then level with a straight edge. Never dip the cup into the bag — that compacts it and adds around 20 grams per cup, which is the single most common cause of dry baking.

All-Purpose Flour — common questions
How many cups is 250 grams of flour?
250 grams of all-purpose flour is about 2.08 cups — near enough 2 cups plus a tablespoon. That assumes flour spooned into the cup and levelled off, at 120 grams per cup.
How do I measure flour without a scale?
Stir the flour in its container to loosen it, spoon it lightly into your measuring cup without shaking or tapping, then level the top with the back of a knife. Never scoop the cup through the bag — that compacts the flour and can add 20 grams per cup.
How many cups is 100 grams?
It depends entirely on the ingredient. 100 grams of all-purpose flour is about 0.83 cups, but 100 grams of honey is only about 0.29 cups, because honey is far denser. Grams measure weight and cups measure volume, so there is no single conversion that works for everything.
Why do different converters give different answers?
Mostly because they assume different measuring techniques. Flour spooned gently into a cup weighs around 120 grams; the same cup dipped straight into the bag can hold 140 grams. Both figures are defensible, so two sites can disagree by 15% and neither is lying. We publish separate figures for each technique rather than picking one.
Are these conversions exact?
No, and no weight-to-volume conversion can be. Density shifts with packing, humidity, grind and brand. Treat every result here as a close approximation. If precision matters, weigh your ingredients.
