Common length units

Light year (ly)

Definition: Light year (symbol: ly) na the distance wey light travel for vacuum for one Julian year, wey equal about 9.4607 trillion kilometers or 9.4607 × 10^15 meters.

History/origin: Astronomers adopt light year as practical way to talk about huge interstellar distances wey go need very big numbers if na kilometers or miles.

Current use: Light years dey mainly for astronomy and science communication to describe distances between stars, nebulae, and other objects outside our solar system.

Nanometer (nm)

Definition: Nanometer (symbol: nm) na one billionth of meter (0.000000001 m or 10^-9 m). Na metric unit wey dem dey use for extremely small length.

History/origin: Nanometer show up for scientific use of metric system as researchers need practical names for very small scales. E become especially common for physics, chemistry, optics, and semiconductor manufacturing.

Current use: Dem dey use nanometers to describe wavelength of light, dimensions of molecules, atomic‑scale structures, and fabrication sizes for electronics and materials science.
