nm is a lot of meanings, here are listed as follows:
1 nanometer =1 nanometer (that is, billionth of a meter), which is about 10 atoms in length. Suppose that a hair has a diameter of 0.05 mm, and it is cut radially into an average of 50,000 strands, each of which is about 1 nanometer thick.
2, nm (metric yarn count) Metric yarn count means. Units of textile warp and weft yarn thickness are collectively referred to; The unit is s. Another British yarn count is: Ne.
3. The nm (short for nautical mile) nautical mile is the international Unit of measure. 1 nautical mile =1.852 km (km) (Chinese standard). Standard symbol n mile. The symbol used in the Legal Unit of Measurement of the People's Republic of China is n mile. It is equal to the length of the arc corresponding to 1 minute of latitude on the Earth's elliptic meridian (one degree equals 60, and a circle is 360 degrees).
4, nm (linux command) The nm command is mainly used to list symbols in certain files. In linux, nm is used to list symbols for object files.
5, nm (wear-resistant abbreviation) wear-resistant material is a large class of special electrical, magnetic, light, sound, heat, force, chemical and biological functions of new materials, is information technology, biotechnology, energy technology and other high-tech fields and national defense construction of important basic materials, but also to transform some traditional industries, such as agriculture, chemical, building materials and so on plays an important role.
nm means nanometer, is a unit of length, symbol nm. 1 nanometer =1 nanometer =10 meters (billionths of a meter), which is about 10 atoms in length.
The length of nm is very fine, only the size of a grain of sand.
nm is the symbolic form of nanometer. 1nm=10^-9 m, symbol nm. 1 nanometer =1 nanometre (billionth of a meter), which is about 10 atoms in length. Suppose that a hair has a diameter of 0.05 mm, and it is cut radially into an average of 50,000 strands, each of which is about 1 nanometer thick.
The main difference between nanotechnology and microelectronics is that nanotechnology studies the control of a single atom or molecule to achieve a specific function of the device, and uses the volatility of electrons to work; The microelectronic technology is mainly through the control of electron groups to achieve its function, is to use the particle nature of electrons to work.
nm means nano, 10nm, 14nm refers to the chip manufacturing process. 1 nanometer =0.0000001 cm can be understood as a chip is a 1 cubic centimeter square, to accommodate the side length of 10nm and 14nm small square, of course, the smaller the side length can store more small square, that is to say, the smaller the process, the unit volume of the chip can store more things.

The unit nM stands for is nmol\/l, read as: nanomoles per liter. n is nano, and the common unit is nm. M stands for \"mol\/l\" read: moles per liter. mole (mole), referred to as mole, formerly known as mole molecule, mole atom, symbol mol, is a unit of matter, is one of the seven basic units of the International System of Units. Every mole of any substance (microscopic matter, such as molecules, atoms, etc.) contains Avogadro's constant (about 6.02×1023) particles. 1mol\/L=1000 mmol\/L1mmol\/L = 0.001 mol\/L2, the chemical equation can express the ratio of the amount and mass of the substance between the reactant and the product. For example: 2H? O? =(lit)=2H? The ratio of O coefficients 2∶1∶2 The ratio of the number of particles 2∶1∶2 The ratio of the amount of matter 2∶1∶2 The ratio of the mass 4∶32∶36 From the above analysis, the ratio of the coefficients of the substances in the chemical equation is the ratio of the amount of matter between them. Using this principle, it is possible to calculate the quantity of each substance according to the chemical equation.
