A light-year is the distance that light travels in a vacuum in one Julian year (365.25 days).

There are approximately 3.725 x 10^20 inches in one light-year, showing the enormous scale difference.

The conversion from inches to light-years involves such vastly different scales that it's impractical for most real-world measurements. Light-years are used for astronomical distances.

10,000,000 inches is equal to approximately 0.0000 light-years, as it's an incredibly small distance compared to a light-year.
