A light-year (abbreviation: ly), sometimes referred to incorrectly as a light year, is a unit of length used informally to express astronomical distances. It is approxi ..more definition+
A variant of the point, equal to 0.3759 mm, or 1/72 of a French Royal inch (27.07 mm), or about 1/68 inch. Didot points are used in Europe. This unit is named after the French printer François Ambroise Didot (1730 - 1804) who defined the "point-based" typographical measurement system.
In relation to the base unit of [length] => (meters), 1 Light Years (ly) is equal to 9461000000000000 meters, while 1 Didot Points (didot point) = 0.000375972222 meters.| 1 Light Years | to common length units |
