About the Grams of Flour to Cups
The Grams of Flour to Cups calculator converts the mass of all-purpose flour into US cups using a fixed ratio of 120 grams per cup. With the default input of 1 gram of flour, it returns 0.008333 cups. Use it to estimate a cup measurement when a recipe lists all-purpose flour in grams.
- Value in grams of flour
- Enter the mass of all-purpose flour in grams; the default value is 1.
Formula and method
c = g / k, where k = 120 grams per US cup; for the default input, c = 1 / 120 ≈ 0.008333 cups.
- cThe calculated volume of all-purpose flour in US cups.
- gThe entered mass of all-purpose flour in grams.
- kThe fixed conversion factor of 120 grams of all-purpose flour per US cup.
Divide the entered mass in grams by 120 to calculate US cups. The default calculation is 1 ÷ 120, displayed as 0.008333 cups after rounding to six decimal places. The reverse conversion row states the fixed relationship of 1 cup to 120 grams of flour.

How to use the Grams of Flour to Cups
- 1Find the mass of all-purpose flour in your recipe or measure it with a kitchen scale.
- 2Enter that mass in the Value in grams of flour field, or leave the default value of 1.
- 3Read the cups result calculated by dividing the entered grams by 120.
- 4Check the forward conversion row: with the default input, 1 gram of flour is approximately 0.008333 cups.
- 5Use the reverse row, 1 cup = 120 grams of flour, to confirm the conversion factor.
Reading your result
The row “cups = 0.008333” shows the calculated US cup amount for the default input. The row “1 grams of flour = = 0.008333 cups” repeats that conversion with the input and output units. The row “1 cups = = 120 grams of flour” shows the reverse unit relationship, not a second result for the entered mass. The repeated equals signs are display formatting; the forward result is rounded.
Limitations
This tool assumes all-purpose flour weighs 120 grams per US cup. Actual flour mass per cup varies with scooping, packing, sifting, moisture, and the flour itself. The fixed factor is not intended for other flour types, other ingredients, or metric and Imperial cups. Six decimal places do not imply that a kitchen cup can measure such a small quantity accurately; weighing flour is more reliable, especially for the default 1-gram quantity.
Common questions
Why does this calculator use 120 grams per cup of flour?+
It uses 120 grams per US cup as its fixed reference for all-purpose flour. This is a cooking convention rather than a universal mass-to-volume equivalence, because flour can be packed more or less densely.
Can I use this calculator for bread flour, whole-wheat flour, or gluten-free flour?+
Not reliably without checking the appropriate grams-per-cup factor. This calculator always divides by 120 and does not adjust for flour type.
Why does 1 gram of flour produce 0.008333 cups?+
One gram is one one-hundred-twentieth of the assumed mass of a cup of all-purpose flour. Dividing 1 by 120 gives a repeating decimal, displayed as 0.008333 cups.
Should I pack flour into the cup to match this conversion?+
No. Packing flour increases the mass held in the cup and can make it inconsistent with the 120-gram assumption. Spoon flour lightly into the cup and level it, or use a scale for a more dependable measurement.
Does the calculator save my information?+
