How much is 9oz of spinach in cups?

Nine ounces of spinach is approximately 10 to 11 cups when fresh and raw, as spinach is very light and has a high volume when leafy. However, if the spinach is cooked, it shrinks significantly, and 9 ounces would yield about 2 to 3 cups. The exact conversion can depend on the specific type and preparation of the spinach.
