Miles (mi) to Light-years (ly) Conversion
Miles
The mile is a unit of length with roots in the Roman mille passuum ("thousand paces"), approximately 1,480 metres. The modern international mile, standardised in 1959, is defined as exactly 1,609.344 metres. It remains the primary unit of road distance in the United States, United Kingdom, and a small number of other countries, and is used in aviation for visibility reporting. The statute mile should be distinguished from the nautical mile (1,852 m), used in maritime and aerial navigation worldwide.
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.
