Feet (ft) to Light-years (ly) Conversion
Feet
The foot is a unit of length equal to exactly 0.3048 metres, defined by the international yard and pound agreement of 1959. Today it is the primary unit of height measurement in the United States and the United Kingdom, and is used in aviation worldwide to express altitude, where flight levels are defined in hundreds of feet. One foot equals 12 inches and one third of a yard.
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.
