In short
One gram of all-purpose flour is 0.008 us cup. Going the other way, one us cup is 125 gram. That works out at 2 gram = 0.016 us cup and 4 = 0.032. The figure comes from all-purpose flour weighing 125 g per US cup — a generic cups-to-grams converter assumes water and will give you the wrong answer here, because volume to weight depends entirely on what is in the cup.

About the Grams to Cups — All-Purpose Flour
How you fill the cup matters more here than for anything else in the kitchen. Dipping the cup straight into the bag compacts the flour and can add 20% — around 25 g per cup — which is the difference between a tender cake and a dry one. The figure used here is the spooned-and-levelled weight: fluff the flour, spoon it in, level with a knife. US recipes and UK recipes disagree: many British sources use 150 g per cup for plain flour because they assume a scooped cup. The figure this page works from is 125 g per US cup, the spooned-and-levelled weight recorded by King Arthur Baking and the USDA food database. Converting gram to us cup for all-purpose flour, the amounts that come up most often are: 25 gram = 0.2 us cup; 50 gram = 0.4 us cup; 75 gram = 0.6 us cup; 100 gram = 0.8 us cup; 150 gram = 1.2 us cup; 200 gram = 1.6 us cup; 250 gram = 2 us cup; 500 gram = 4 us cup; 1000 gram = 8 us cup.
What people use it for
- Following a US recipe with a kitchen scale instead of cup measures.
- Scaling a recipe up or down without compounding measuring error.
- Converting a European recipe written in grams into cups.

The maths behind it
This tool uses us cup = gram × 0.008, derived from all-purpose flour weighing 125 g per US cup. Every intermediate value is shown on screen, so the result can be checked by hand.

Where this tool stops
Volume-to-weight conversion is inherently approximate. Humidity, brand, how finely something is milled and how long it has sat in the cupboard all shift the figure by a few per cent.
Frequently asked questions
Why do different websites give different grams per cup of flour?
Because they measured differently. Spooned and levelled gives about 125 g; scooped from the bag gives 145–150 g; sifted first gives closer to 115 g. None is wrong, but a recipe rarely says which one it used — which is the whole argument for weighing flour instead.
Why does a cup of all-purpose flour not weigh the same as a cup of water?
Because a cup measures volume and a scale measures weight, and the two only agree for water. All-purpose flour has its own density — 125 g per US cup — so any generic volume converter gives the wrong answer here.
How much does the way I fill the cup matter?
Enormously, and this is the ingredient where it matters most. Scooping straight from the bag compacts the flour and can add 20% — about 25 g on a 125 g cup — which is the difference between a tender crumb and a dry one. The figure here is spooned and levelled: fluff it, spoon it in, level with a knife. A scale removes the question entirely.
Is a US cup the same as a UK or metric cup?
No. A US cup is 236.6 ml, a metric cup is 250 ml and an old UK cup is 284 ml. These pages use the US cup, because that is what US recipes mean.
