Nanometer

A Nanometer (symbol: nm) is a unit of length in the metric system, equal to one billionth of a meter (0.000000001 m). The name combines the prefix nano- with the parent unit name meter.

Definition[edit | edit source]

The nanometer is defined as one billionth of a meter, where a meter is defined by the International Bureau of Weights and Measures as the length of the path travelled by light in vacuum during a time interval of 1/299,792,458 of a second.

Usage[edit | edit source]

The nanometer is often used to express dimensions on the nanoscale, a scale of size that is relevant in many fields of science such as physics, chemistry, biology, material science, and technology.

Applications[edit | edit source]

In technology, the nanometer is commonly used to specify the wavelength of ultraviolet light, the size of microscopic objects, such as bacteria, and the dimensions of integrated circuit components. In the semiconductor industry, the sizes of the components are often given in nanometers.
