Cups → Grams

Convert cups to grams for common ingredients.

How this calculator works

Converts US cups to grams for common baking ingredients — flour, sugar, butter, etc. Weight depends on ingredient density, so 1 cup of flour ≠ 1 cup of sugar.

For accuracy, weigh ingredients on a kitchen scale.

Professional bakers weigh nearly everything rather than measuring by volume specifically because of this density problem — a scale removes the guesswork of how tightly an ingredient was packed into the cup.

Example

1 cup of flour ≈ 125 g. Other ingredients vary — pick from the dropdown.

Frequently asked questions

Why do the same 'cup' weights differ online?

Density of packed vs sifted, and different flour brands vary. Weighing is always more consistent than measuring by volume.

US cups vs metric cups?

US = 240 ml, metric = 250 ml, UK = 284 ml. This tool uses US cups.

Does it matter if I scoop or spoon flour into the cup?

Yes, noticeably — scooping directly from the bag packs the flour more densely than spooning it in loosely, which can add up to 20-25% more flour by weight for the same cup measurement.
