ConverterCups to Grams Converter
Estimate the mass of a measured ingredient when a recipe gives U.S. cups but your kitchen scale uses grams. Choose the ingredient and measuring state before entering the cup quantity.
All four choices are USDA household-measure references, so the gram result is an estimate. Accepts decimals, fractions such as 1/2, mixed fractions such as 1 1/2, and scientific notation. Use a decimal point; commas are rejected. Results display up to two decimals.
The Ingredient Is Part Of The Formula
The calculation is grams = cups x selected grams per U.S. household cup. This page does not apply one flour-based factor to every food. Its four choices state the ingredient and preparation used for the estimate.
For one cup, the reference estimates are 125 g for spooned-and-level unsifted all-purpose flour, 115 g for sifted all-purpose flour, 200 g for granulated sugar, and about 237 g for water. These are source-backed household measures, not guaranteed weights for every product or measuring technique.
Check The Measure Before Using It
- Match the recipe's ingredient and preparation wording; sifted and unsifted flour are not interchangeable assumptions.
- Level a dry measuring cup unless the source says packed or uses another method.
- For sensitive baking or unsupported ingredients, use the recipe author's weight or weigh the ingredient directly.
- Keep the selected assumption with the converted number when sharing or scaling a recipe.

Frequently Asked Questions
Cups measure volume and grams measure mass. The mass of one cup changes with ingredient density and preparation, so the converter needs a declared ingredient assumption.
The ingredient options use a U.S. household cup basis. Metric and Imperial cup conventions can produce different values.
Yes. The field accepts decimals, simple fractions, mixed fractions, and scientific notation. Use a decimal point rather than a comma.
No. It is an ingredient-specific estimate based on the selected grams-per-cup reference. Scooping, sifting, packing, moisture, and ingredient variation can change the actual mass.
