Meters (m) to Light-years (ly) Conversion
Meters
The metre is the SI base unit of length, defined since 1983 as the distance light travels in a vacuum in exactly 1/299,792,458 of a second, anchoring its definition to a universal physical constant rather than any material artefact. Introduced by the French Academy of Sciences in 1791 as one ten-millionth of the distance from the equator to the North Pole, the metre became the cornerstone of the metric system and is today the official unit of length in every country that has adopted SI. In science and engineering, virtually all derived units of length, area, volume, and many physical quantities are expressed in terms of the metre.
Light-years
The light-year is a unit of astronomical distance equal to the distance that light travels in a vacuum in one Julian year (365.25 days), approximately 9.461 × 10¹⁵ metres. Despite containing the word "year," it is strictly a unit of distance, not time. The nearest star system, Alpha Centauri, is approximately 4.37 light-years away, while the observable universe extends approximately 46 billion light-years in every direction.
