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.

Foot (ft)

Definition: The foot is an imperial and US customary unit made of 12 inches. Since standardization, one ft equals exactly 0.3048 m.

History/origin: Many societies used foot-like measures because the body offered a handy reference. Modern English-speaking standards later replaced local variation with a fixed international value.

Current use: Ft is used for room dimensions, ceiling height, elevation, aircraft altitude, human height, sports measurements, construction plans, and real estate listings.
