How many lbs of pinto beans do you cook to feed 150 people?

12.5 pounds of dry pinto beans are required for 150 servings of cooked beans. The standard serving size is one-half cup. One pound of dried pinto beans equals two cups of dried beans, or six cups of cooked beans.

If using canned beans, 50 fifteen-ounce cans of beans are required. Each can contains 1 ½ cups, or three servings. For people to be able to have seconds or a larger serving size, increase the amount of dried beans to 18.75 pounds and the amount of canned beans to 75 cans. This allows for every person to have a three-quarter cup of beans.
