How this converter works
Cups measure volume while grams measure mass, so the correct factor depends on ingredient density. Choose the ingredient that best matches what you are measuring.
Worked example
One US cup of all-purpose flour is estimated at 120 grams; one cup of water is about 236.588 grams.
