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:
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 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 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 nanometer is used in different countries for different applications, depending on their level of development and innovation in nanotechnology. For example:
Example Conversions of Nanometer to Other Units
Here are some example conversions of nanometer to other units of length:
Meter - Unit of Distance / Length
Unit Symbol / Abbreviation: m
Where the unit used in the World:
The meter is used as a unit to measure medium distances or lengths.
Definition of the Unit:
The meter (metre in UK spelling) is a unit of length/distance in the metric system (SI Unit system) equivalent to the length of the path travelled by light during a time interval of 1/299,792,458 of a second (in vacuum, defined since 1983).
History of the Unit:
As a result of the French Revolution in 1789, the old units of measure that were associated with the monarchy were replaced by the new units. The new unit of length was introduced which became known as the meter. In 1795 the meter was defined as 1/10,000,000 part of the quarter of a meridian, passing through Paris. The meter gained popularity in continental Europe during the nineteenth century, particularly in scientific field, and was officially adopted as an international measurement unit in 1875. In 1960 the meter was defined as 1,650,763.73 wavelengths of light from a specified transition in krypton-86. In 1983 the final definition of meter was accepted as length of the path travelled by light in a vacuum in 1/299,792,458 of a second.
Where it's used:
The meter is commonly used in different trades and industries (for examle in machinery manufacturing), on road signs to indicate vehicle hight limits, the distance to short travel to a given location (for example in automotive GPS navigation voice prompts), on maps to indicate small scale, for vehicle, vessels and aircragt dimensions in industry and trade. It is also the most popular unit for describing the retail estate distances and measurements (room sizes, floor measurements and so on).
Equivalents in other units and scales:
1 m is equivalent to 3.28084 ft or 1.09361 yd.
