What does one light year represent?

One light year is the distance light travels in vacuum in one Julian year, about 9.4607 × 10^15 metres.

Why convert light years to gigameters?

Converting light years to gigameters translates very large cosmic distances into units useful for solar system and interplanetary scales.

Is a gigameter used for measuring interstellar distances?

No, gigameters are more appropriate for interplanetary distances within the Solar System rather than vast interstellar scales.
