How big is a nano meter?
 

Your fingernails grow one nano meter per second. That's small. :winkwink:

A nanometer is a unit of spatial measurement that is 10-9 meter, or one billionth of a meter. It is commonly used in nanotechnology, the building of extremely small machines. :2 cents: :winkwink:

A nanometer is about the width of 10 atoms.

indeed, that's small...

its very small indeed. Hope that helps :winkwink:
