100,000,000 nanometers is equivalent to approximately 0.0000 light-years. This is an extremely small fraction of a light-year.

Nanometers measure incredibly tiny distances at the microscopic level, while light-years measure vast distances across space. The difference in scale is immense.

Nanometers are used to measure dimensions in nanotechnology, such as the size of atoms, molecules, viruses, and components in advanced electronics.

A light-year is used in astronomy to measure the distances between stars and galaxies, representing the distance light travels in one year.
