Formula
The gram weight is the USDA FoodData Central household cup for the ingredient you pick. All-purpose flour is 125 g (FDC 168894), granulated sugar 200 g (FDC 169655), butter 227 g (FDC 173410), honey 339 g (FDC 169640), rolled oats 156 g (FDC 169705), and raw long-grain white rice 185 g (FDC 168877).
cups = grams / USDA grams per cup
Use the cups-to-grams page when you start with cups. The volume page still will not tell you the grams.
Assumptions
- The cup is the USDA household cup used in those records.
- The ingredient is the plain food named in the list.
- The result is a kitchen weight, not a laboratory density at a stated temperature.
