Question: 1 can pinto beans equals how many cups?
Answer: 1 Answer. According to the Kitchen Companion, a terrific general handbook which I recommend, 1 lb (about 2 cups) of dried beans is roughly 6 to 7 cups cooked beans, and one 15oz can of cooked beans is roughly 1.75 cups drained, making it equivalent to 1/4 to 1/3 lbs ( or 1/2 to 3/4 cup) dried.
