Centimeters (cm) to Nanometers (nm) Conversion
Centimeters
The centimetre is a unit of length equal to one hundredth of a metre (10⁻² m), derived using the SI prefix centi- (from Latin centum, meaning hundred). It is widely used in everyday measurement of body height, garment sizing, and small objects, and is the standard unit in medicine, tailoring, and interior design. In the CGS (centimetre-gram-second) system that preceded modern SI, the centimetre served as the fundamental unit of length, giving rise to derived units such as the dyne and erg still encountered in physics literature.
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.
