A light-year is the distance light travels in a vacuum in one Julian year (365.25 days). It's approximately 9.46 trillion kilometers or 5.88 trillion miles.

One light-year is equal to 10,346,675,415,573,053 yards.

While light-years are standard for astronomical distances, converting to yards can sometimes help in conceptualizing the immense scale in more relatable, albeit still very large, human-scale units for specific contexts.

It's not a common practical conversion for everyday use, but it's useful in specific scientific or educational contexts where a vast distance needs to be expressed in a unit like yards, even if the resulting number is huge.
