A light-year is approximately 9.46 trillion meters (9.46 x 10^15 meters).

Light-years measure incredibly vast cosmic distances, while 5,000,000 meters is a relatively short distance on an astronomical scale.

5,000,000 meters converts to approximately 0.0000 light-years, indicating it's an extremely tiny fraction of a light-year.

Light-years and parsecs are commonly used for interstellar and intergalactic distances because meters would result in astronomically large and unwieldy numbers.
