In a Nanometer Scale?

A nanometre (nm) is 10⁻⁹ metres, which is one-thousandth of a micrometre, or one-billionth of a metre. This is the scale at which we measure atoms and the molecules they make.

What does nanometer measure?

A nanometer (nm) is a unit of length equivalent to one billionth (10-9) of a meter. For comparison, a single sheet of paper is approximately 100,000 nanometers thick and a strand of DNA is 2.5 nm across.

How many atoms are in a nanometer?

There are about 20 atoms along this line, so one nanometer is about the width of 2 silicon atoms, and the gate length of a 20nm NAND flash chip would be 40 atoms across.
