Grams to cups calculator

Frequently asked questions

Why does the same number of grams give different cup amounts for different ingredients?

Each ingredient has a different density, so the same mass fills a different volume. A cup of water weighs roughly 237 g, while a cup of all-purpose flour weighs around 125 g because flour packs less tightly.

How accurate is a grams-to-cups conversion?

It is a practical kitchen estimate, not a laboratory measurement. The actual weight of a cup varies with how the ingredient is scooped, settled, or sifted, so results can differ by 5–15% from what you measure.

Does this use U.S. cups or metric cups?

The calculator uses the U.S. customary cup, which is approximately 237 milliliters. Metric and Australian cups are slightly larger, so adjust if your recipe specifies a different cup standard.

What if my ingredient is not in the list?

Select the ingredient with the closest density profile as a rough guide, or weigh the ingredient directly on a kitchen scale for the most reliable result.
