Part of the Nanotechnology glossary: 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. This was last updated in September 2005. Contributor(s): Ian Pulham.
Itâs hard to imagine just how small nanotechnology is. One nanometer is a billionth of a meter, or 10 -9 of a meter. Here are a few illustrative examples: 1  There are 25,400,000 nanometers in an inch. 2  A sheet of newspaper is about 100,000 nanometers thick.
