All-purpose flour is the everyday flour used in many kitchens for cookies, muffins, cakes, pancakes, biscuits, quick breads, sauces, and basic doughs. Because it is used in so many recipes, a reliable cups-to-grams conversion is especially helpful.
A cup of all-purpose flour can weigh differently depending on whether it is spooned, leveled, sifted, packed, or scooped straight from the bag. Measuring by grams gives you a more repeatable amount and helps avoid dry doughs, dense cakes, or crumbly cookies.

How to Convert All-Purpose Flour Cups to Grams
To convert all-purpose flour from cups to grams, multiply the number of cups by 120. This page uses 1 cup of all-purpose flour = 120 grams, which is a practical average for everyday baking.
grams = cups x 120 For example, if a recipe calls for 2 cups of all-purpose flour, the calculation is 2 x 120 = 240 grams. If it calls for 1/2 cup, the calculation is 0.5 x 120 = 60 grams.
How to Convert All-Purpose Flour Grams to Cups
To convert all-purpose flour from grams to cups, divide the gram amount by 120. This is useful when a recipe gives metric measurements but you want an approximate cup measurement.
cups = grams / 120 For example, 100g of all-purpose flour is 100 / 120 = 0.83 cups. This is close to 13.3 tablespoons. Grams are still more reliable than cups because small measuring differences can change the texture of the final recipe.
Why All-Purpose Flour Cup Weight Can Vary
All-purpose flour settles in the bag or container over time. If you scoop directly with a measuring cup, the flour can compact and weigh more than expected. If you spoon and level gently, the same cup usually weighs less.
Brand, protein level, humidity, storage, and sifting can also change how much flour fits into a cup. This converter uses 120g per cup as a practical average for spoon-and-level all-purpose flour, but important recipes are still best measured with a kitchen scale.
How to Measure All-Purpose Flour Accurately
The most accurate way to measure all-purpose flour is with a digital kitchen scale. Place your bowl on the scale, tare it to zero, and add flour until you reach the gram amount listed in the recipe.
If you are using cups, fluff the flour first, spoon it gently into the measuring cup, and level the top with a straight edge. Do not tap the cup or press the flour down.
Avoid scooping directly from the flour bag because it can pack extra flour into the cup. Too much flour can make cookies dry, cakes dense, muffins heavy, and pancakes thicker than intended.
All-Purpose Flour Baking Notes
All-purpose flour is designed to work across many recipes. It is not as strong as bread flour and not as delicate as cake flour, which makes it a flexible choice for everyday baking.
Because all-purpose flour is used in both tender baked goods and simple doughs, accuracy matters. A small difference may not ruin a sauce or pancake batter, but it can be more noticeable in cookies, cakes, biscuits, and quick breads.
When adapting a recipe, keep the flour measurement consistent first. If the batter or dough still seems too wet or too dry, adjust liquid gradually rather than changing the flour amount too aggressively.
All-Purpose Flour vs Other Flour Weights
All-purpose flour is often estimated around 120g per cup when spooned and leveled. Bread flour is usually a little heavier by cup, while cake flour is lighter and more delicate.
If a recipe specifically says bread flour, use a bread flour conversion because the cup weight and baking behavior are different. If it says cake flour, use a cake flour conversion because sifted and fine-milled flour can measure lighter by volume.
whole wheat flour can be close in cup weight, but it absorbs liquid differently because it contains bran and germ. almond flour and coconut flour behave very differently and should not be converted using an all-purpose flour cup weight.
Store all-purpose flour in an airtight container in a cool, dry place. For longer storage, refrigeration or freezing can help maintain freshness, but let chilled flour come back toward room temperature before baking.
All-Purpose Flour Cup Size Notes
Most US baking recipes use a standard US cup, so this calculator uses 120g per cup for all-purpose flour. If your recipe uses a metric or imperial cup, the estimated flour weight may be slightly different because the cup volume changes.
| Cup Type | Volume | Approx. Weight | Best For |
|---|---|---|---|
| US customary cup | 236.6 mL | 120g | Common in US recipes |
| US legal cup | 240 mL | 122g | Used for nutrition labeling |
| Metric cup | 250 mL | 127g | Common in many metric recipes |
| Imperial cup | 284 mL | 144g | Larger than US and metric cups |
| Australian cup | 250 mL | 127g | Same volume as a metric cup |
