All-purpose flour, Cups to Grams & Grams to Cups
1 cup of all-purpose flour = 125 grams · 100g = 0.8 cups
Also known as plain flour.
All-purpose flour is the reference point most baking recipes are written around, but it is also the ingredient where cup measuring goes most wrong. A cup can weigh anywhere from 120g to over 150g depending on whether you spoon it in or dip the cup straight into the bag, which compacts the flour. The 125g figure here assumes the spoon-and-level method that King Arthur and most US recipe developers use.

| UK imperial cup | 284 ml | 150 g | Older British recipes |
| Japanese cup | 200 ml | 106 g | Japan |
Unless a recipe says otherwise, US recipes mean the US cup and Australian/UK recipes mean the 250 ml metric cup. The tables higher up this page use the US cup.

How many cups is 100g, 200g or 300g of all-purpose flour?
Because one cup of all-purpose flour weighs about 125 grams, you can convert any weight to cups by dividing by 125. So 100g of all-purpose flour is about 0.8 cups, 200g is about 1.6 cups, 250g is about 2 cups, and 300g is about 2.4 cups. For any other amount, type the grams straight into the converter above and switch it to show cups.
How to measure all-purpose flour accurately
For the most reliable baking results, weigh all-purpose flour (also called plain flour) on a kitchen scale rather than scooping by volume. One US cup of all-purpose flour weighs about 125 grams (4.41 oz), but the exact figure changes with how tightly it's packed and the brand. Scooping straight from the bag compacts all-purpose flour and can leave you 15 to 20% over, so spoon it into the cup and level it off for the closest match to the figures above. Use the tables for quick reference, or the converter for any custom amount in cups, grams, ounces or tablespoons.
Tip: Stir the flour first, spoon it loosely into the cup, then level with a knife. Never tap or pack the cup — that is how a recipe ends up with 20% too much flour and a dry, dense crumb.
