One light-year is approximately 31,040,026,246,782 feet.

5 light-years is equal to 155,200,131,233,595,808.0000 feet.

While light-years are standard for astronomical distances, converting to feet can help some people conceptualize the sheer magnitude of these distances in a familiar unit.

Astronomers primarily use light-years or parsecs for cosmic distances. Converting to feet is more for illustrative purposes to convey scale to a general audience.
