Nautical miles (nmi) to Light-years (ly) Conversion
Nautical miles
The nautical mile is a unit of length equal to exactly 1,852 metres, adopted internationally in 1929. Unlike most length units, it is geometrically derived: it corresponds to one arcminute (1/60 of a degree) of latitude, making it naturally suited to navigation on the spherical surface of the globe. Speed in nautical miles per hour is expressed in knots.
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.
