Nanometer: A Unit of Length

Definition of the Nanometer

A nanometer or nanometre (international spelling) is a unit of length in the International System of Units (SI), equal to one billionth (short scale) of a meter (0.000 000 001 m) and to 1000 picometres. One nanometer can be expressed in scientific notation as 1 × 10-9 m, and as 1/1 000 000 000 metres.

History of the Nanometer

The nanometer was formerly known as the millimicrometre - or, more commonly, the millimicron for short - since it is 1/1000 of a micrometre, and was often denoted by the symbol mµ or, more rarely, as µµ. The name combines the SI prefix nano- (from the Ancient Greek nanos, “dwarf”) with the parent unit name metre (from Greek metron, “unit of measurement”).

The nanometer was first used in the late 19th century by scientists who studied light and optics, such as Lord Rayleigh and Albert Michelson. They used interferometers to measure wavelengths of light in nanometers. In the early 20th century, the nanometer was also used by physicists who studied atomic and molecular structures, such as Ernest Rutherford and Niels Bohr. They used spectroscopy and scattering experiments to determine the sizes and distances of atoms and molecules in nanometers. In the mid-20th century, the nanometer was also used by chemists and biologists who studied colloids and macromolecules, such as The Svedberg and Linus Pauling. They used ultracentrifuges and X-ray diffraction to measure the sizes and shapes of particles and polymers in nanometers.

In the late 20th century, the nanometer became more widely used as a result of the development of nanotechnology, which is the manipulation of matter at the nanoscale. Nanotechnology involves various fields of science and engineering, such as electronics, materials, medicine, energy and environment. Nanotechnology enables the creation of new devices and systems with novel properties and functions that depend on their nanoscale dimensions.

How to Convert Nanometer

To convert nanometer to other units of length, one can use the following conversion factors:

  • 1 nanometer = 10-9 meter
  • 1 nanometer = 10-6 millimeter
  • 1 nanometer = 10-3 micrometer
  • 1 nanometer = 10 angstrom
  • 1 nanometer = 3.937 × 10-8 inch
  • 1 nanometer = 3.281 × 10-9 foot

To convert other units of length to nanometer, one can use the inverse of these conversion factors.

Where Nanometer is Used

The nanometer is often used to express dimensions on an atomic scale and mostly in the molecular scale. For example:

  • The diameter of a helium atom is about 0.06 nm
  • The diameter of a water molecule is about 0.28 nm
  • The thickness of a DNA strand is about 2 nm
  • The diameter of a ribosome is about 20 nm
  • The thickness of a cell membrane is about 10 nm

The nanometer is also commonly used to specify the wavelength of electromagnetic radiation near the visible part of the spectrum: visible light ranges from around 400 to 700 nm. For example:

  • The wavelength of violet light is about 400 nm
  • The wavelength of green light is about 550 nm
  • The wavelength of red light is about 700 nm

The nanometer is also used to describe typical feature sizes in successive generations of the ITRS Roadmap for miniaturized semiconductor device fabrication in the semiconductor industry. For example:

  • The transistor gate length in Intel’s Pentium processor (1993) was about 800 nm
  • The transistor gate length in Intel’s Core processor (2006) was about 65 nm
  • The transistor gate length in Intel’s Tiger Lake processor (2020) was about 10 nm

The nanometer is used in different countries for different applications, depending on their level of development and innovation in nanotechnology. For example:

  • In Japan, nanotechnology is used for improving the performance and efficiency of solar cells, batteries, fuel cells, sensors, and displays.
  • In China, nanotechnology is used for developing new materials, such as carbon nanotubes, graphene, and nanocomposites, for various industries, such as aerospace, automotive, and textile.
  • In India, nanotechnology is used for addressing social and environmental challenges, such as water purification, health care, agriculture, and energy.

Example Conversions of Nanometer to Other Units

Here are some example conversions of nanometer to other units of length:

  • 1 nm = 10-9 m
  • 10 nm = 10-8 m
  • 100 nm = 10-7 m
  • 1000 nm = 10-6 m = 1 µm
  • 10 000 nm = 10-5 m = 10 µm
  • 100 000 nm = 10-4 m = 100 µm
  • 1 000 000 nm = 10-3 m = 1 mm
Nanometers also can be marked as Nanometres.

Microinch: A Unit of Length

The microinch is a unit of length that is equal to one millionth of an inch (0.000001 inch). It is a non-SI unit of measurement that is mainly used in engineering and manufacturing fields. The symbol for microinch is µin or µ". The microinch is also a derived unit in the British imperial and US customary systems of measurement.

The microinch is most commonly used when expressing small distances or dimensions, such as the surface roughness or flatness of materials and parts. The microinch is also used for measuring the wavelength of light and other electromagnetic waves.

In this article, we will explore the definition, history, usage and conversion of the microinch as a unit of length.

Definition of the Microinch

The microinch is a unit of length that is equal to one millionth of an inch (0.000001 inch). It is defined as 25.4 nanometers or 2.54 × 10^-8 meters by international agreement in 1959. One inch is equal to 25.4 millimeters or 0.0254 meter.

The definition of the microinch has changed over time, as different standards and methods of measurement were developed by various countries and organizations. The current definition of the microinch as based on the meter was agreed upon by an international treaty in 1959.

History of the Microinch

The origin of the microinch as a unit of length can be traced back to the early 20th century, when it was introduced by the American Society for Testing and Materials (ASTM) as a standard for measuring surface roughness. Surface roughness is a measure of how smooth or irregular a surface is, which affects its friction, wear and corrosion properties.

The microinch was adopted by other countries and industries that followed the American system of measurement, such as Canada and Japan. It was also incorporated into the ANSI/ASME B46.1 standard for surface texture in 1985.

The microinch was also used by some optical scientists and engineers to measure the wavelength of light and other electromagnetic waves. For example, the visible spectrum of light ranges from about 4,000 to 7,000 microinches.

Usage of the Microinch

The microinch is a unit of length that is used for measuring small distances or dimensions, such as the surface roughness or flatness of materials and parts. For example:

  • Measuring the smoothness or roughness of metal surfaces, such as steel, aluminum and copper.
  • Measuring the flatness or curvature of glass surfaces, such as lenses, mirrors and windows.
  • Measuring the thickness or diameter of thin films, coatings and wires.
  • Measuring the accuracy or tolerance of machined parts, such as gears, bearings and shafts.

The microinch is commonly used in engineering and manufacturing fields, especially in precision machining, metrology and quality control. Some examples are:

  • Measuring the surface finish of machined parts, such as turned, milled and ground surfaces.
  • Measuring the surface profile of textured surfaces, such as honed, lapped and polished surfaces.
  • Measuring the surface geometry of complex surfaces, such as grooved, fluted and serrated surfaces.
  • Measuring the surface defects of defective surfaces, such as scratches, pits and dents.

The microinch is also used for measuring the wavelength of light and other electromagnetic waves. For example:

  • Measuring the color or frequency of visible light, infrared light and ultraviolet light.
  • Measuring the polarization or phase of coherent light, such as laser light and holographic light.
  • Measuring the interference or diffraction patterns of interfering light, such as interferometric light and diffractive light.
