Detailed explanation-1: -A nanometer is a unit of measurement for length just as you have with meters and centimeters. A nanometer is one billionth of a meter, 0.000000001 or 10-9 meters. The word nano comes from the Greek word for “dwarf.” The term nanoscale is used to refer to objects with dimensions on the order of 1-100 nanometers (nm).

Detailed explanation-2: -Just how small is “nano?” In the International System of Units, the prefix “nano” means one-billionth, or 10-9; therefore one nanometer is one-billionth of a meter.

Detailed explanation-3: -Nanometer is an unit to measure very small length. Generally it is used to measure wavelength, size of particles in air, microorganism etc. nanometer or 1 n m is equivalent to 10-6 m m .

Detailed explanation-4: -Nanotechnology is the development and use of techniques to study physical phenomena and develop new devices and material structures in the physical size range of 1-100 nanometres (nm), where 1 nanometre is equal to one billionth of a meter.

Detailed explanation-5: -A nanometer (nm) is equal to one-billionth of a meter.
