Nanometer is a measurement unit. The unit length is equal to approximately one billionth of one meter. Nanometer is highly used as scale to build complex, tiny and atomic scale. It computes the electronic components in nanotechnology. For measuring small things such as a molecule or an atom, nanometers are used. The term is used in the behalf of small computing devices like transistor, which is embedded into a processor and integrated circuit. A semi-conductor based transistor’s size is measured in nanometers. Every microchip has transistors, which is 100 nanometer in width and it can accommodate greater than one billion transistors in a microchip.

Integrated circuit like computer processor consists of microscopic components. To measure the size of the microscopic components, nanometers are useful in various way. The various eras of the processors are denoted in nanometer. The number identifies the distance within the components of CPU and the transistor. More transistors will be placed if the numbers of the transistors are small. It allows more efficient and faster design of the processor.

All the measurements of metric based on the measurement of meter. By inspecting any measuring tape or ruler, it can be seen that the marking number are for meter, millimeters, centimeters and millimeter. With a steady hand and a mechanical pencil, it is easy to draw a line one millimeter or centimeter apart but measuring one nanometer or draw a line of one nanometer is not possible by using the scale.

Nanometer is denoted as ‘nm’. The unit length of nanometer is equal to approximately one billionth of one meter. The word “nano” came from ancient Greek and the word meter came from Greek. The unit is used to measure the atomic scale, as they are tiny in size. Nanometer is equivalent to 0.000000001 meter.

One billionth meter is equivalent to the size of 3 to 6 atoms, which are placed consecutively or it is a size of the width of a DNA strand. The thickness of single human hair is within 50,000 and 100,000. For measuring these types of miniature things, nanometer is used. Some example of natural and artificial things that is measured by nanometer. Nanometer comes up with researching glow light frequently. It is a simple unit of measurements of spatial. When it is used to horticulture lighting, the nanometer is the unit measurement of any natural or any artificial sources.

Natural things: Some examples of natural things, which are exist in that size are ant (5 mm), dust mite (200 μm), human hair (60-120 μm), red blood cell (7-8 μm), fly ash (10-20 μm), ATP synthase (10 nm), DNA (2-1/2 nm), silicon atoms (0.078 nm) and so on.

Artificial things: Some example of artificial or human made things, which are exist in that size are head of pin ( 1-2 mm), micro electro mechanical devices ( 10-100 μm), x-ray zone plate ( 35 nm), carbon buckyball (1 nm), carbon nanotube (1.3 nm), quantum coral (14 nm) and so on.
