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.
A nanometer is one billionth of a meter. When a processor is made, it is made with millions or even billions of transistors which are nothing but switches that switch on and off, 1 is on and 0 is off, which is the binary code the computer uses for everything.
