About these units
Nanometer (nm)
- Definition
- A nanometer (nm) is one billionth of a meter, the scale of atoms, molecules, and wavelengths of light.
- History
- It combines the SI prefix "nano-" (one billionth) with the meter and became common with the rise of nanotechnology.
- Current use
- Nanometers measure the wavelengths of visible light (about 380–750 nm) and the feature sizes of modern microchips.
Light Year (ly)
- Definition
- A light-year (ly) is the distance light travels in one year in a vacuum, about 9.46 trillion kilometers.
- History
- The concept arose in the 19th century as astronomers sought an intuitive way to express the vast distances between stars.
- Current use
- Light-years express distances to stars and galaxies in astronomy and popular science.
