I know all of that. But it isn't the point. It's the opposite of the point.The definition of "magnification ratio" is the ratio between the size of the image projected on sensor/film, and the real size. It's an optical attribute of the lens. And should remain constant no matter what sensor is used. Think about it this way, will the max magnification ratio change if you move a magnifying glass around? Another example, take a specific macro lens, at max magnification, take a picture of a grain of rice, will the size of projected image size change because sensor size changes?
So, talking about equivalence of "max magnification ratio" is wrong in the first place. There is no equivalence, it always remain constant.
