What does one light year represent?

One light year is the distance that light travels in vacuum during one Julian year, about 9.4607 × 10^15 meters.

Why convert light years to meters?

Converting light years to meters provides a standard metric measurement useful for scientific and engineering calculations.

Is it practical to use meters for light year distances?

Due to the extremely large scale of light years, expressing them directly in meters can be impractical for everyday use.
