A nanometer (eng. nanometre, nm) is a unit of measurement of length equal to one billionth of a meter. It is used to measure very small distances, such as the size of atoms and molecules. In physics, the nanometer is commonly used to describe the size of particles and also to measure the wavelength of light.
One nanometer is equal to one billionth of a meter (1 µm = 1000 nm, 1 cm = 10 mm = 0.01 m, 1 km = 1,000,000 m).
Nanometer has several other designations, such as nm (nanometer), nm (nanometer), nm (nanometer), 1 nm (one nanometer), 1 nm (one nanometer).
In biology, the nanometer is used as a unit of measurement for the size of cells and other biological objects. For example, yeast cells can range in size from 5 to 150 nanometers.
Nanometers are also used in technology to measure the size of microchips and other devices. For example, wavelengths of light in the range of 300 to 400 nanometers are used in infrared spectroscopy to determine the composition of materials.
One of the most interesting applications of the nanometer is to use it to create new materials with unique properties. For example, carbon nanotubes can be incredibly strong and lightweight, making them ideal for use as materials for nanoelectronics.
Thus, a nanometer is a very small unit of measurement used to measure distances and to work with new materials and devices.
Nanometer
In nanotechnology, the unit of measurement used is *nanometer* (*nm*), equal to ten to the ninth power of meters (10^-9 m) or 1 nanometer (from English nanometer, n[aː]nomɪtr). The term was introduced into scientific literature in 2007. The nanometer is one of the smallest units of measurement used in atomic physics and chemistry. In works of the late 20th century it was also called an immersion millimeter (German: Immersion Millimeter), and previously simply a micrometer.
