Cups to Grams Flour Converter
Convert cups to grams for flour with a baking-friendly reference based on all-purpose flour, kitchen scales, and recipe prep.
All-purpose flour
This page is ingredient-specific. It uses 1 cup all-purpose flour ≈ 120 g and 1 tsp flour ≈ 2.6 g and should be treated as an approximate kitchen reference.
120 g
1 cup all-purpose flour ~= 120 g
Approximate conversion based on spooned-and-leveled all-purpose flour.
About converting cups to grams for flour
Why flour needs its own conversion
Flour is one of the easiest baking ingredients to mismeasure because a cup of flour does not have one perfectly universal weight. The result changes depending on whether the flour is spooned into the cup, scooped directly from the bag, or packed down more firmly than intended. That is why this page fixes the assumption to spooned-and-leveled all-purpose flour instead of pretending every cup of flour always weighs the same amount.
Kitchen formula and assumption
This converter uses a practical baking reference of 1 US cup of all-purpose flour being about 120 grams. That means 2 cups of flour comes out around 240 grams, while half a cup is about 60 grams. For home baking, that assumption is widely used because it helps line up cup-based recipes with gram-based kitchen scales without overcomplicating the result.
When this page is useful
This is most helpful when a recipe from the United States lists cups but you prefer to bake by weight, or when you are scaling a recipe and want more consistency than cup measuring usually gives. It is also useful when comparing recipes from different sites, checking ingredient prep before mixing dough, or translating an older family recipe into a scale-friendly format.
Ingredient assumption
flourThis page assumes spooned-and-leveled all-purpose flour, where 1 US cup is treated as about 120 grams. Because flour compacts differently depending on how it is scooped, the result should be treated as a practical baking estimate rather than an exact lab measurement.
Density note: 1 cup all-purpose flour ≈ 120 g and 1 tsp flour ≈ 2.6 g. This is an approximate kitchen reference, not a universal volume-to-weight rule for every ingredient.

Important note
approximateCooking conversions like cups to grams and grams to teaspoons depend on ingredient density, packing, humidity, and how the ingredient is measured. This page is locked to all-purpose flour so the assumption stays clear and the result is less misleading than a universal converter.
Common questions
3 answersHow many grams are in 1 cup of all-purpose flour?
This page uses an approximate baking reference of 1 US cup of all-purpose flour being about 120 grams.
Why is cups to grams for flour only approximate?
Flour density changes depending on how it is scooped, leveled, or packed, so the gram value is a kitchen estimate rather than a universal constant.
When should I use cups to grams flour conversion?
It is most useful when a recipe lists flour in cups but you want to weigh ingredients for more consistent baking results.
