LightYears (ly)
A light-year, alternatively spelled light year, is a large unit of length used to express astronomical distances and is equivalent to about 9.46 trillion kilometers (9.46U+00d71012 km), or 5.88 trillion miles (5.88U+00d71012 mi). As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in a vacuum in one Julian year (365.25 days). Because it includes the time-measurement word year, the term light-year is sometimes misinterpreted as a unit of time.

The kilometre, symbol km, spelt kilometer in American English, is a unit of length in the International System of Units (SI), equal to one thousand metres. It is now the measurement unit used for expressing distances between geographical places on land in most of the world, notable exceptions are the United States and the United Kingdom where the statute mile is the unit used.
