Enter a weight in grams, select your cooking ingredient (flour, sugar, butter, water, and 15+ more), and get the equivalent measurement in US cups. The Grams to Cups Converter accounts for each ingredient's density so your baking and cooking conversions are always on point.

Because grams measure weight while cups measure volume, the conversion depends on each ingredient's density. For example, 100g of flour is much fluffier and less dense than 100g of honey, so flour takes up more cup volume. Always use an ingredient-specific converter for accurate results.
100 grams of all-purpose flour is approximately 0.8 cups (US). This assumes the flour is spooned into the cup rather than scooped, which can pack the flour and change the measurement. Bread and cake flours differ slightly due to varying densities.
200 grams of all-purpose flour equals roughly 1.6 cups (US). For whole wheat flour or bread flour, the cup amount will vary slightly because those flours have different densities than standard all-purpose flour.
500 grams of all-purpose flour is approximately 4 cups (US). This is a common measurement for large bread or cake recipes. Remember that density differences between flour types mean bread flour or whole wheat flour may yield slightly different cup volumes.
It depends entirely on the ingredient. One US cup of water weighs about 237g, one cup of all-purpose flour weighs about 125g, one cup of granulated sugar weighs about 200g, and one cup of butter weighs about 227g. There is no single universal answer — density determines the weight.
The formula is: cups = grams ÷ (236.588 × density in g/mL). You need to know the density of your ingredient. For example, all-purpose flour has a density of about 0.528 g/mL, so 100g ÷ (236.588 × 0.528) ≈ 0.8 cups. Using this calculator is much faster and handles the density lookup for you.
250 grams converts to different cup amounts depending on the ingredient: roughly 2 cups of all-purpose flour, 1.25 cups of granulated sugar, about 1.06 cups of water, or just over 1 cup of butter. Always select the specific ingredient for a correct conversion.
Yes — cup sizes vary by country. A US cup is 236.6 mL, a metric cup (used in Australia, Canada) is 250 mL, and a UK imperial cup is 284 mL. This converter uses the standard US cup. If your recipe uses metric or UK cups, the result will differ slightly, so check your recipe's country of origin.
