Convert cups to grams for common baking ingredients using ingredient-specific cup weights. Choose an ingredient, enter the number of cups, and get an approximate gram weight instantly.
Cup weight changes by ingredient, so select the ingredient before relying on the result.

Select an ingredient and enter cups.
Your approximate gram weight will appear here.
Cup-to-gram conversions are approximate because the weight of a cup can vary with the ingredient, measuring method, density, packing, brand, and preparation.

A cups to grams converter changes a recipe measurement from volume to weight. It is especially useful when a recipe lists an ingredient in cups but you prefer to weigh that ingredient on a kitchen scale in grams.
The important part is the ingredient. A cup measures volume, while a gram measures weight, so there is no single gram value that works for every cup. One cup of flour is much lighter than one cup of honey, even though both fill the same cup volume.
To convert cups to grams, multiply the number of cups by the approximate grams in one cup of the selected ingredient.
grams = cups × grams per cup
Example: using this site's all-purpose flour reference of 125 g per cup, 2 cups × 125 g = approximately 250 g. The calculator performs the same calculation automatically after you choose an ingredient.
Ingredients have different densities. Fine sugar crystals, fluffy flour, solid butter, and thick honey do not contain the same amount of mass in the same cup volume. That is why a useful cups-to-grams tool needs an ingredient-specific reference value rather than one universal conversion number.
Dense ingredients usually weigh more per cup than light, airy ingredients.
Scooping, spooning, leveling, sifting, or packing can change how much ingredient fits into a cup.
Brand, grind, moisture, temperature, and preparation can create small real-world differences.
This chart uses the same ingredient database as the calculator, so updates to a reference value automatically update the tool and the chart together.

Values are practical baking reference values for this site and should be treated as approximate, not universal scientific constants.
Here are a few frequently useful conversions generated from the same database used by the calculator.
Grams can be especially helpful in baking because a scale measures ingredient weight directly. Cup measurements can vary when an ingredient is packed, scooped, sifted, or settled differently. If a recipe provides gram measurements, using a kitchen scale can make it easier to repeat the same quantity consistently.
When a recipe only gives cups, this converter provides a practical estimated gram amount based on the ingredient you select. For precision-sensitive baking, also follow any measuring instructions given by the original recipe author.
Using this converter's all-purpose flour reference, 1 cup is approximately 125 g. Other flour types can have different cup weights, and the result can also change with the measuring method.
For all-purpose flour at 125 g per cup, 2 cups × 125 g equals approximately 250 g. Select a different flour in the calculator when your recipe uses another type.
It depends on the sugar. In this tool, 1 cup granulated sugar is approximately 200 g, brown sugar is approximately 220 g, and powdered sugar is approximately 125 g.
No. Cups measure volume and grams measure weight. Different ingredients have different densities, so the gram weight of one cup changes with the ingredient.
Multiply the number of cups by the grams-per-cup reference for that ingredient. The formula is: grams = cups × grams per cup.
Because equal volumes can contain different amounts of mass. Density, particle size, packing, moisture, and preparation all affect how much an ingredient weighs in a cup.
No. They are practical approximations. The actual weight can vary with ingredient type, brand, how the cup is filled, whether an ingredient is packed or sifted, and other preparation differences.
