Again, it depends on six ounces of what. Six ounces of pasta will not be the same volume as six ounces of water. Maybe you mean FLUID OUNCES, which is a measure of water and similar liquids. A FLUID OUNCE measures volume (as well as weight) and is not the same as an ounce. Six fluid ounces will equal 3/4 (or 0.75 - learn metric already) cups.
