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.

Inch (in)

Definition: The inch is a US customary and imperial length unit. Its modern value is exactly 25.4 mm, with 12 inches making one foot.

History/origin: Inch measurements began with body and object references, then moved through English standards before the international yard and pound agreement fixed the inch in metric terms.

Current use: In is common for screens, tools, hardware, lumber, pipes, fabric cuts, tire sizes, product specs, and many household measurements in the United States.
