When applied to phenomena and abstract objects, it describes existence in the world as we perceive it. Lengths scales generally considered macroscopic roughly fall in the range 1 mm–1 km.The term macroscopic may also refer to a "larger view", namely a view only available from a large perspective. A macroscopic position could be considered the "big picture".
