10000 yards is equal to 0.0000 light-years. This is because light-years are used to measure vast cosmic distances, and yards are a relatively small unit of measurement.

A light-year represents an immense distance, while a yard is a human-scale measurement. Therefore, it takes an incredibly tiny fraction of a light-year to equal a few thousand yards.

While not a common practical calculation for everyday life, this conversion is useful in educational contexts to demonstrate the extreme difference in scale between Earth-based measurements and astronomical distances.

Yards are a unit of length in the imperial system, while light-years are a unit of distance used in astronomy, representing the distance light travels in one year. They measure vastly different scales.
