A third of a millimeter (0.33 mm) is quite small—about the thickness of a fine human hair, which typically ranges from 0.1 to 0.2 mm. To visualize it, consider that a standard pencil lead is around 0.5 mm in diameter; thus, a third of a millimeter would be noticeably thinner than that. In practical terms, it’s difficult to see without magnification, as it's much smaller than most common objects.
