How Many Grams in a Cup of Flour? (Full Chart)
July 14, 2026
There are about 125 g of all-purpose flour in one US cup when spooned and levelled. Cake flour is lighter at around 115 g and bread flour denser at about 130 g. Scooping packs in extra, so spoon into the cup and level off.
Wondering how many grams in a cup of flour there are? For all-purpose flour the answer is about 125 g per US cup — but it changes for bread, cake and wholemeal flour. Here is the full breakdown, plus a free converter.
Flour cups to grams chart
| Flour type | 1 cup | ¾ cup | ½ cup | ⅓ cup | ¼ cup |
|---|---|---|---|---|---|
| All-purpose (plain) flour | 125 g | 94 g | 63 g | 42 g | 31 g |
| Bread (strong) flour | 130 g | 98 g | 65 g | 43 g | 33 g |
| Cake flour | 115 g | 86 g | 58 g | 38 g | 29 g |
| Whole wheat flour | 120 g | 90 g | 60 g | 40 g | 30 g |
| Self-raising flour | 125 g | 94 g | 63 g | 42 g | 31 g |
Based on a US cup (240 ml). Spoon-and-level; scooping straight from the bag can add 20–30 g per cup.
How many grams in a cup of flour?
The number of grams in a cup of flour depends on the type. Denser flours weigh a little more; lighter, finer flours weigh a little less. Always spoon flour into the cup and level it off — scooping packs it down and adds weight.
Grams in a cup of flour by type
| Type of flour | 1 cup in grams |
|---|---|
| All-purpose (plain) | 125 g |
| Bread flour | 127 g |
| Cake flour | 114 g |
| Wholemeal / whole wheat | 120 g |
| Almond flour | 96 g |
Why weighing flour matters
Measuring flour by weight is far more accurate than by cup. Two people can scoop the same cup and get 20–30 g difference, which is enough to make a cake dry or dense. A kitchen scale removes the guesswork.

Why a cup of flour isn’t always 125 g
For all-purpose (plain) flour, a US cup is about 125 g when spooned in and levelled. But that figure moves with the type of flour and how you measure it. Cake flour is lighter at roughly 115 g per cup, while bread (strong) flour packs denser at around 130 g. Humidity, sifting and even how long the flour has been sitting all nudge the number. Scoop the cup straight into the bag and you can end up with 150 g — 20% too much.
The right way to measure flour
To hit that 125 g reliably without scales:
- Fluff first: stir the flour in its container so it is not compacted.
- Spoon, don’t scoop: spoon it loosely into the cup.
- Level: sweep the top flat with a knife.
- Sifted flour: if a recipe says “1 cup sifted flour”, sift then measure — sifted flour is lighter, so you get fewer grams per cup.
The classic error — dipping the cup and packing in extra flour — is the number one cause of dry, tough cakes and dense bread. When it matters, weigh it, or cross-check with our cups to grams converter.
