A metric prefix is a unit prefix that precedes a basic unit of measure to indicate a multiple or submultiple of the unit. All metric prefixes used today are decadic.Each prefix has a unique symbol that is prepended to any unit symbol.
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. Examples. Three gold atoms lined up are about one nanometer (nm) long.

Nanotechnologies are based on physical processes which occur on a scale of nanometres (see nanoscopic scale). [1]The nanometre is often used to express dimensions on an atomic scale: the diameter of a helium atom, for example, is about 0.06 nm, and that of a ribosome is about 20 nm.
Arguably the biggest potential application of nanocircuits deals with computers and electronics. Scientists and engineers are always looking to make computers faster. Some think in the nearer term, we could see hybrids of micro-and nano-: silicon with a nano core—perhaps a high-density computer memory that retains its contents forever. [20]

Micro (Greek letter μ, mu, non-italic) is a unit prefix in the metric system denoting a factor of 10 −6 (one millionth). [1] It comes from the Greek word μικρός (mikrós), meaning "small". [2] It is the only SI prefix which uses a character not from the Latin alphabet.
