Grams of Flour to Cups Converter (g to cups)

Recipes from Britain and most of Europe give flour in grams. Without a scale, the gram figure has to be turned into cups, and that step depends on how much flour a cup holds. This converter assumes 125 g per US cup, the USDA weight for all-purpose flour spooned into the cup and leveled, so 250 g becomes 2 cups and 100 g becomes 0.8 cup.

Going from grams to cups is the less reliable direction, because the gram figure in the recipe is exact and the cup is only an estimate of it. Fill the cup the way the 125 g figure assumes: spoon the flour loosely into the cup and level it with a straight edge, without tapping or packing. For amounts under a quarter cup, tablespoons are easier; at the same density each one holds about 7.8 g.

How to use this tool

1. Type a value in the Gram of Flour box to see it in cups, or type in the Cup box to convert the other way.
2. Press ⇄ to swap the two units, or Load example for a typical value.
3. Check the charts below for common values; for other units, open the Cooking Measure converter.

Formula

cups = grams of flour ÷ 125 (all-purpose flour, USDA)

grams of flour = cups × 125 (all-purpose flour, USDA)

Both factors come from the converter's own definitions: 1 cup = 125 grams of flour and 1 gram of flour = 0.008 cups (shown to 12 significant digits).

Example

Two conversions worked with the same factors the converter uses:

300 g flour = 2.4 cup

1.5 cup = 187.5 g flour

Quick mental estimate

Multiply the grams by 8, then divide by 1,000: 300 g → 2,400 → 2.4 cups, and 450 g → 3,600 → 3.6 cups. That is the same as dividing by 125, so the shortcut matches the chart exactly. For the leftover decimal, 0.1 cup is 1.6 tablespoons.

Use the converter or the charts when the exact figure matters.

The two units

Gram of Flour (g flour): This estimate uses 125 g per US cup of unsifted, spooned all-purpose flour, the portion weight in USDA’s Nutritive Value of Foods table (2002). Packing, sifting and flour type change the mass, so weigh the flour when accuracy matters.

Cup (cup): The US customary cup used in American recipes holds 8 US fluid ounces or 16 tablespoons, exactly 236.5882365 mL. US nutrition labels round it to 240 mL, and the metric cup used in Australia and many other countries is 250 mL.
