Decimeters (dm)
Definition
A decimeter (dm) is a metric unit of length equal to one tenth of a meter (0.1 m) or 10 centimeters.
History
The decimeter is part of the original metric system. While less commonly used than centimeters or meters, it has practical significance — 1 cubic decimeter equals exactly 1 liter.
Current use
Decimeters are occasionally used in European educational contexts and in volumetric calculations (1 dm³ = 1 L). They appear in some building specifications and packaging dimensions.
Nanometers (nm)
Definition
A nanometer (nm) is a metric unit of length equal to one billionth of a meter (10⁻⁹ m). It is part of the International System of Units (SI).
History
The nanometer became important in the 20th century with advances in microscopy and semiconductor technology. The prefix 'nano' comes from the Greek word 'nanos' meaning dwarf.
Current use
Nanometers are essential in nanotechnology, semiconductor manufacturing (chip node sizes like 5 nm, 3 nm), molecular biology (DNA strand width ~2.5 nm), and light wavelength measurement (visible light: 380–700 nm).
