One nanometre (nm) is 10−9 metre. The micrometre (μm), which equals 10−6 metre, is often used to describe infrared radiation. Nanometre | unit of measurement | Britannica
The nanometre (international spelling as used by the International Bureau of Weights and Measures; SI symbol: nm) or nanometer (American spelling) is a unit of length in the International System of Units (SI), equal to one billionth (short scale) of a metre (0.000 000 001 m) and to 1000 picometres.
Nanotechnology is a part of science and technology about the control of matter on the atomic and molecular scale - this means things that are about 100 nanometres across. Nanotechnology includes making products that use parts this small, such as electronic devices, catalysts, sensors, etc.

Recent Examples on the Web This means that the glasses protect against all types of UV light with wavelengths under 400 nanometers, which includes UVA (which has a wavelength between 315 and 400) and UVB (which has a wavelength between 280 and 315).
Jul 30, 2021 · 88. What is a Nanometer? Hint: Extremely small machines use it. By. Stanley Goodner. Updated on July 30, 2021. A nanometer (nm) is a unit of length in the metric system, equal to one billionth of a meter (1 x 10-9 m). Many have likely heard of it before–it’s frequently associated with nanotechnology and the creation or study of very tiny things.
One nanometer (nm) is one billionth, or 10 −9, of a meter. By comparison, typical carbon–carbon bond lengths, or the spacing between these atoms in a molecule, are in the range 0.12–0.15 nm, and a DNA double-helix has a diameter around 2 nm.
Overview. A nanometre ( American spelling: nanometer, symbol nm) ( Greek: νάνος, nanos, dwarf; μετρώ, metrό, count) is a unit of length in the metric system, equal to one billionth of a metre (i.e., one millionth of a millimetre), which is the current SI base unit of length.
