Meter to Nanometer Converter

Nanometers are the natural unit for atomic-scale phenomena. Physicists, materials scientists, and nanotechnologists work at this scale when designing microchips, optical components, and nanostructures.

Visible light ranges from 400 nm (violet) to 700 nm (red). Infrared is 700 nm to ~1 mm, and ultraviolet is below 400 nm. Knowing exact nanometer values is critical for filter design, laser selection, and spectroscopy.

A "5 nm node" doesn't measure actual feature size anymore—it's a market label. Modern chips use 5 nm, 3 nm, and 2 nm nodes, each requiring extreme-UV lithography and atomic-scale precision.

A nanometer is to a meter what a marble is to Earth. A human hair is ~70,000 nm wide. Viruses are 20-300 nm. A single atom is roughly 0.1-0.3 nm.
