USDA FoodData Central publishes composition for cooked pinto, kidney, and black beans. That is the cite for what a cup of beans is. It is not a rule for Texas red or Cincinnati.
How to use the number
If you cook beans in the pot, you are in Homestyle, Cincinnati, Springfield, or a home pot that wants them. CASI and ICS Traditional Red cups forbid beans. That lives on the beans debate. Soak and simmer times come from the bag or a published method, not from this page inventing a clock.
Pinto stays an oval mottled bean in a chef hat. Dry pinto beans in the pantry are the ingredient.
