Meaning: nanometer is a unit of length The concept of 6 nanometers means less energy consumption and better performance. Nanometer (symbol :nm), that is, nanometer, is a unit of measurement of length. 1 nanometer =10 to the minus 9 meters. One nanometer is four times the size of an atom, much smaller than the length of a single bacterium. Individual bacteria are virtually invisible to the naked eye, measuring about five microns in diameter with a microscope.
Suppose that the diameter of a single hair is 0.05 mm, and divide it into an average of 50,000 axial strands
