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.

Inch: A Unit of Length Used in the US Customary System

The inch (in) is a unit of length used in the US customary system, which is one of the systems of measurement used in the United States and some other countries. The inch is equal to 1/12 of a foot or 2.54 centimeters. The inch is also a derived unit in the imperial system, which is the official system of measurement for the United Kingdom and some other Commonwealth countries. The symbol for inch is in or ″. The inch is used for measuring short distances and dimensions, such as the length of a nail or the width of a finger. The inch is named after the Latin word uncia, meaning one-twelfth. In this article, we will explore the definition, history, usage and conversion of the inch as a unit of length.

Definition of Inch

The inch is a unit of length that is equal to 1/12 of a foot. It is defined as 25.4 millimeters. The foot is defined as 0.3048 meters.

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

History of Inch

The origin of the inch as a unit of length can be traced back to ancient times, when it was used as a measure of length based on the human body. The word inch comes from the Latin word uncia, meaning one-twelfth. It referred to one-twelfth of a Roman foot, which was about 29.6 millimeters.

The inch was also used as a measure of length by other civilizations, such as the Anglo-Saxons, who used it as one-third of a palm or one-twenty-fourth of an ell. The Anglo-Saxon inch was about 25 millimeters.

The inch was adopted by other countries that followed the English system of measurement, such as the United States and Canada. It was also incorporated into the imperial system, which was established by an act of Parliament in 1824. The imperial system was based on seven base units that could be derived from natural and traditional units. The inch remained as a derived unit in the imperial system, but it was no longer recommended for use in scientific and technical fields.

Usage of Inch

The inch is a unit of length that is used for measuring short distances and dimensions, such as the length of a nail or the width of a finger.

The inch is commonly used in everyday life, especially in countries that follow the US customary system. Some examples are:

  • Measuring the size and shape of objects and tools.
  • Measuring the height and weight of people and animals.
  • Measuring the distance and time between places and events.
  • Measuring clothing sizes and shoe sizes.

The inch is also used in some scientific and technical fields, such as:

  • Measuring the diameter and circumference of circles and spheres.
  • Measuring the thickness and density of materials.
  • Measuring the pressure and temperature of gases and liquids.

How to Convert Inch to Other Units of Length in the US Customary System

To convert inch to other units of length in the US customary system, we need to know the relationship between inch and other units. Here are some common units and their equivalent values in inches:

  • 1 yard = 36 inches
  • 1 mile = 63,360 inches
  • 1 mil = 0.001 inch

To convert inch to any of these units, we need to multiply or divide by the appropriate factor. For example, to convert 10 inches to feet, we need to divide by 12:

10 inches / 12 = 0.833 feet

To convert 10 inches to miles, we need to divide by 63,360:

10 inches / 63,360 = 0.000158 miles

To convert 10 inches to mils, we need to multiply by 1000:

10 inches x 1000 = 10,000 mils

How to Convert Inch to Other Units of Length in the SI System
