<P> The nanometre ( International spelling as used by the International Bureau of Weights and Measures ; SI symbol : nm ) or nanometer ( American spelling ) is a unit of length in the metric system , equal to one billionth ( short scale ) of a metre ( 6991100000000000000 ♠ 0.000 000 001 m ) . The name combines the SI prefix nano - ( from the Ancient Greek νάνος , nanos , `` dwarf '' ) with the parent unit name metre ( from Greek μέτρον , metrοn , `` unit of measurement '' ) . It can be written in scientific notation as 6991100000000000000 ♠ 1 × 10 m , in engineering notation as 1 E − 9 m , and is simply 1 / 7009100000000000000 ♠ 1000000000 metres . One nanometre equals ten ångströms . When used as a prefix for something other than a unit of measure ( as in `` nanoscience '' ) , nano refers to nanotechnology , or phenomena typically occurring on a scale of nanometres ( see nanoscopic scale ) . </P>
