Nanometers (nm) to Millimeters (mm) Conversion
Nanometers
The nanometre is a unit of length equal to one billionth of a metre (10⁻⁹ m) and represents the fundamental scale of atomic and molecular structures. The diameter of a hydrogen atom is approximately 0.1 nm, a DNA double helix is about 2 nm wide, and a typical protein ranges from 1 to 100 nm. The nanometre is the primary unit in nanotechnology, materials science, and optics: the wavelength of visible light spans roughly 380–700 nm.
Millimeters
The millimetre is a unit of length equal to one thousandth of a metre (10⁻³ m), derived using the SI prefix milli- (from Latin mille, thousand). It is the standard unit for precision measurements in engineering, manufacturing, and medicine, where tolerances are routinely specified to the nearest millimetre or fraction thereof. In meteorology, rainfall is universally measured in millimetres, where 1 mm of rainfall corresponds to 1 litre of water per square metre of surface area.
