Nanometer (nm)
The nanometre (nm) is one billionth of a metre. Visible light spans roughly 380–780 nm.
Symbol: nm
Quantity: length and distance
SI relation: 1 nm = 1 × 10⁻⁹ m (exact)
Derivation: 1 nm = 10⁻⁹ m
Exact: yes, by definition
Typical uses
- Wavelengths of light (UV, visible, near-IR)
- Semiconductor process nodes and thin films
- Nanoparticles and molecular dimensions
