How to Calculate
Converting from cups (volume) to grams (weight) requires the ingredient density. For example, a teaspoon of flour weighs less than a teaspoon of honey.
Cups to Grams Conversion Chart
Because cups measure volume and grams measure weight, an exact chart depends on the ingredient. The table below shows common volume-to-weight values for water.

Frequently Asked Questions
How many grams are in 1 cup?
It depends on the ingredient's density, since you are converting between volume and weight.
Is a US cup the same as an Imperial cup?
In many cases, US customary and Imperial measurements differ slightly. Our calculator defaults to US Customary measurements, which are standard for most modern recipes.
Why does ingredient density matter for c to g?
A cup is a unit of volume, while grams is a unit of weight. To convert accurately between them you must account for how tightly the ingredient is packed, which is its density.
