A light-year is the distance that light travels in a vacuum in one Julian year (365.25 days). It's a unit used to measure astronomical distances.

There are 372,480,314,960,629,952 inches in one light-year.

While light-years are standard for cosmic distances, converting to inches can help visualize the sheer scale in a more relatable, albeit very large, unit for certain contexts or comparisons.

Astronomers typically use light-years, parsecs, or astronomical units (AU) for measuring distances. Converting to inches is more for conceptual understanding or specific display purposes rather than standard scientific practice.
