A light-year is the distance that light travels in a vacuum in one Julian year (365.25 days). It is approximately 9.461 trillion kilometers or 5.879 trillion miles.

While light-years are standard for astronomical distances, conversion to yards can help visualize the immense scale in a (much) smaller, though still incredibly large, terrestrial unit.

One light-year is approximately 1.0346675 x 10^16 yards.

This conversion is primarily for conceptual understanding or specific scientific visualizations, as the distances are astronomical and far beyond everyday experience.
