A light-year is the distance light travels in a vacuum in one Julian year (365.25 days). It's a unit of astronomical distance.

One light-year is approximately 9.461 trillion meters.

Converting light-years to meters allows us to express vast cosmic distances in a standard, relatable unit used in everyday science and engineering.

While astronomers primarily use light-years, this conversion is useful for general understanding and for specific scientific contexts where meters are the preferred unit.
