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.

Yard (yd)

Definition: The yard is a customary length unit equal to 3 feet. Under the modern definition, one yd is exactly 0.9144 m.

History/origin: Yard measures developed in English practice for cloth, land, and everyday distances, then became tied to the standardized foot and inch system.

Current use: Yd appears in American football fields, golf distances, fabric sales, landscaping estimates, garden layouts, and some UK or US outdoor measurements.
