Cups to Grams

Please choose a cooking ingredient. A density is required for converting between cups and grams, as some ingredients are denser than others.
Convert between cups and grams for popular baking and cooking ingredients. From sugar, flour and butter to nuts and fruits.

How many grams are in a cup?

The number of grams in one cup is dependent upon the ingredient, due to differing ingredient density. For flour, 1 cup equates to around 125g. For sugar, 1 cup equals around 200g. For butter, 1 cup equates to around 227g.

To calculate the grams from a recipe given in cups, it's vitally important to consider what the ingredient is. A cup of ball-bearings will weigh much more than a cup of feathers (though both make for delicious pancake toppings, my toothless cousin tells me). Therefore, there's no single gram equivalent for a cup; salt can be as heavy as 300g, while fresh breadcrumbs would only come to 60g.

How to convert cups to grams

To convert cups to grams multiply your cups figure by 236.588 and again by the ingredient density (in g/ml). If your density is not in g/ml, you will need to convert it first.

grams = cups × 236.588 × ingredient density (in g/ml or g/cm³)

Let's look at an example of how to convert cups to grams (using a US cup).

Example: Mabel wants to convert 3 cups of all-purpose flour to grams. She finds that her all-purpose flour has a density of 0.529 g/cm³. Her calculation is therefore as follows:

3 × 236.588 × 0.529 = 375.5 grams.
