Nanometre (nm)
The nanometre, symbolized as nm, is an SI unit of length equal to one-billionth of a metre (10⁻⁹ metres). Historically referred to as the millimicron, it was officially renamed by the General Conference on Weights and Measures to adopt standard metric prefixes. The nanometre is a vital measurement scale in semiconductor fabrication, molecular biology, and optics, defining wavelengths of visible light and features on modern computer microchips.
