Detailed explanation-1: -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-2: -A nanometer is one billionth of a meter.

Detailed explanation-3: -A nanometer (nm) is equal to one-billionth of a meter.

Detailed explanation-4: -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-5: -The smallest thing you can see with your naked eye is about 40-50 microns, or about the width of a human hair. So now, 1000 times smaller than that is nanometer. We can’t see it with the human eye, unless we have a very powerful microscope. Remember, a nanometer is a billion times smaller than a meter (you!).
