Take the length of the equator on this map, double that distance and you have the width of a human hair. For this is the world’s smallest world map, with the 40,000 kilometre-long equator reduced to a mere 40 micrometres.The smallest features on the map, corresponding to 100 kilometres, are about 100 nanometres wide.More info at the link. I decided that actually trying to represent the description might give it a little more impact... the scaly thing is a human hair, and the finer fiber is spider silk.
