nanometre
Light wavelength measure
A nanometre is one billionth of a metre—a unit so small it measures things invisible to the eye.
Atoms are fractions of a nanometre across; DNA strands are about two nanometres wide.
The scale is essential in nanotechnology, semiconductor manufacturing, and molecular biology: The chip's transistors are built at the 3-nanometre scale.
Also spelled nanometer.
