Formula for cups to grams
Grams = cups × grams per cup
Example: 2 cups of granulated sugar multiplied by 198 grams per cup equals 396 grams.
King Arthur Baking is the primary source for baking ingredient weights. NIST is used for the US customary cup volume. USDA FoodData Central is used where an ingredient is outside the main baking chart. These references are documented in the downloadable Sources PDF.
We select one documented working standard per ingredient and do not silently mix standards between pages or tools. Where a value naturally varies, the ingredient state and note explain the limitation.
If a recipe publisher supplies its own weight for one cup, follow that recipe-specific value because it reflects the way the recipe was tested.
What does grams per cup mean?
It is the reference weight of one US cup for a clearly named ingredient state. The value is used in the formulas grams divided by grams per cup and cups multiplied by grams per cup.
