Nano (symbol n) is a unit prefix meaning one billionth. Used primarily with the metric system, this prefix denotes a factor of 10 −9 or 0.000 000 001. It is frequently encountered in science and electronics for prefixing units of time and length. Three gold atoms lined up are about one nanometer (nm) long.

Jan 13, 2010 · Eight original SI prefixes were officially adopted: deca, hecto, kilo, myria, deci, centi, milli, and myrio, derived from Greek and Latin numbers. Initially, all prefixes were represented by lowercase symbols.

A table of all metrix prefixes: their values, symbols and definitions. Useful for scientists, mathematicians or laymen to understand measures and sizes.

Nano is a SI unit prefix meaning one billionth. Used primarily with the metric system, this prefix denotes a factor of 10⁻⁹ or 0.000000001. It is represented by the prefix nano or the symbol n. The prefix derives from the Greek term νᾶνος (Latin nanus), meaning dwarf.
