How many pounds of pinto beans do you need to buy to feed 120 people?

To feed 120 people, you typically need about 1/4 to 1/2 cup of cooked pinto beans per person. Since 1 cup of dry pinto beans yields approximately 2 to 2.5 cups of cooked beans, you would need about 6 to 12 pounds of dry beans, depending on the serving size. A safe estimate would be around 8 to 10 pounds to ensure everyone is adequately fed.
