Baking recipes from different countries use different measurement systems. European and professional recipes list ingredients by weight in grams, while many American recipes use volume cups. This converter bridges both systems using ingredient-specific densities so your measurements are accurate every time.
- Enter your amount. Type the quantity you want to convert. For grams to cups, enter the gram weight from your recipe. For cups to grams, enter the cup amount.
- Select your ingredient. The converter uses density values specific to each ingredient. A cup of honey weighs 340 grams, while a cup of cocoa powder weighs only 86 grams. Choosing the right ingredient is essential for accuracy.
- Choose your direction. Select Grams to Cups or Cups to Grams depending on which direction your recipe requires.
- Read your results. The primary result shows the converted amount to two decimal places. The breakdown panel also shows the equivalent in tablespoons and teaspoons, plus the density reference used for that ingredient.

About the Grams to Cups Converter
Volume and weight are not interchangeable without knowing the density of the ingredient. One cup always equals 16 tablespoons or 48 teaspoons, but its gram weight changes with every ingredient. All-purpose flour weighs 120 grams per cup when spooned and leveled, but packed flour can weigh significantly more. The densities used in this tool follow standard culinary measurement references used in professional baking.
Weighing ingredients with a kitchen scale is more precise than measuring by volume, especially for flour and cocoa where scooping can pack significantly more than the reference density. If your recipe lists grams, use the gram measurement. If it lists cups, this converter gives you the accurate gram equivalent so you can weigh it out instead. All calculations run entirely in your browser. No data is stored or transmitted.
Frequently Asked Questions
How many grams is 1 cup of flour?
One cup of all-purpose flour weighs approximately 120 grams when measured using the spoon-and-level method. Bread flour weighs about 130 grams per cup, cake flour about 115 grams, and whole wheat flour about 120 grams. The variation comes from differences in protein content, grind size, and how tightly the flour packs. Scooping directly from the bag can add 20-30 grams per cup compared to spooning flour into the cup and leveling off the top.
How many grams is 1 cup of sugar?
One cup of granulated white sugar weighs 200 grams. Brown sugar packed firmly into a cup weighs about 220 grams. Powdered (confectioners) sugar, which is much lighter and prone to packing, weighs around 120 grams per cup. Because sugar densities vary significantly by type, always check which kind of sugar your recipe calls for before converting.
Why do grams to cups conversions differ by ingredient?
A cup is a unit of volume, always equal to 236-240 milliliters depending on the standard used. Grams measure mass. The relationship between the two depends on density: how much mass is packed into a given volume. Dense ingredients like honey (340 g/cup) or salt (288 g/cup) weigh far more per cup than light, airy ingredients like cocoa powder (86 g/cup) or rolled oats (90 g/cup). This is why a single conversion factor does not work across different baking ingredients.
Should I measure baking ingredients by weight or by cup?
Professional bakers and most serious home bakers prefer weight measurements because they are more consistent and accurate. Volume measurements like cups depend on how the ingredient is packed, whether it has settled, and the exact size of the measuring cup being used. For ingredients like flour, even a small difference in technique can change the amount by 20% or more. If you have a kitchen scale, measure by grams. If you do not, use this converter to get accurate gram equivalents from cup measurements in your recipe.
