at scales within direct human experience, from the micrometric (106 m, top left) to the multi-kilometric (105 m, bottom right).
Comparison of sizes of semiconductor manufacturing process nodes with some microscopic objects and visible light wavelengths. At this scale, the width of a human hair is about 10 times that of the image.[1]

To help compare different orders of magnitude this page lists some items with lengths between 10−6 and 10−5 m (between 1 and 10 micrometres, or µm).

Distances shorter than 1 µm
Distances longer than 10 µm
