How to Convert Cups to Grams

To convert a cup measurement to a gram measurement, multiply the volume by 236.588236 times the density of the ingredient or material.

You can use this simple formula to convert:

grams = cups × 236.588236 × ingredient density

Thus, the volume in grams is equal to the cups multiplied by 236.588236 times the density of the ingredient or material.

For example, here's how to convert 5 cups to grams for an ingredient with a density of 0.7 g/mL.
5 c = 5 × 236.588236 × 0.7 = 828.058828 g

Cups and grams are both commonly used to measure cooking ingredients.

For cooking applications, most chefs suggest measuring dry ingredients by weight rather than volume to improve accuracy in the measurements.[1] The density of dry ingredients can vary for a variety of reasons, such as compaction.

The best way to ensure an accurate conversion is to use a scale. When a scale is not available, a calculator like the one above is a good way to estimate the volume to weight conversion.

For cooking and baking ingredients, you can get more specific results using our butter, flour, sugar conversion calculators.

The cup is a unit of volume equal to 16 tablespoons or 8 fluid ounces. The cup should not be confused with the metric cup or the teacup, which are different units of volume. One cup is equal to just under 236.6 milliliters, but in nutrition labeling, one cup is equal to 240 milliliters.[2]

The cup is a US customary unit of volume. Cups can be abbreviated as c, and are also sometimes abbreviated as C. For example, 1 cup can be written as 1 c or 1 C.


A gram is the mass/weight equal to 1/1,000 of a kilogram and is roughly equivalent to the mass of one cubic centimeter of water.

The gram, or gramme, is an SI unit of weight in the metric system. Grams can be abbreviated as g; for example, 1 gram can be written as 1 g.
