Answer: 1nm is equal to 0.000000001 m or 10⁻⁹m.

The scientific notation to express one nanometre is 1×10⁻⁹ m. It is used to express dimensions on an atomic scale. The wavelength of electromagnetic radiation near the visible part of the spectrum is expressed in a nanometer. The name Nanometre combines the SI prefix nano (derived from the Greek word ‘nanos’ means dwarf) and the parent unit name metre (derived from the Greek word ‘meteron’ means the unit of measurement). The diameter of ribosomes, helium atoms, etc. is measured in nanometres.

Summary:

1 nanometer (nm) is Equal to How Many Meters (m)?

1nm is equal to one billionth of a metre which is 0.000000001 m. The unit is used for measuring dimensions that are smaller than microscopic.
