Answer 1

Explanation:

I think in the question we are asking two different items to be converted into one another.

One light year is the distance traveled by light in vacuum in one Julian year.
It has dimensions of Distance. It is `approx9.461xx10^15 m`

It is an informal unit of distance used in day-to-day talk to express astronomical distances.
Scientific unit is parsec (symbol: pc, which is `approx 3.26` light-years)

One earth year is unit of time.
