Common length units

Light year (ly)

Definition: A light year (symbol: ly) is the distance light travels in a vacuum in one Julian year, equal to about 9.4607 trillion kilometers or 9.4607 × 10^15 meters.

History/origin: The light year was adopted by astronomers as a practical way to express vast interstellar distances that would otherwise require extremely large numbers in kilometers or miles.

Current use: Light years are used mainly in astronomy and science communication to describe distances between stars, nebulae, and other objects beyond our solar system.

Micrometer (µm)

Definition: The micrometer is a metric unit equal to 0.000001 m. A million micrometers fit into one meter, placing it between nanometers and millimeters.

History/origin: Microscope work and precision manufacturing needed a unit smaller than the millimeter, and µm became the preferred SI-style name for what many people once called a micron.

Current use: µm is common in lab imaging, machining tolerances, film thickness, pollen and bacteria sizes, textile fibers, filters, coatings, and dust-particle specifications.
