What does one light year represent?

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

Why use the Sun's radius as a unit?

The Sun's radius provides a stellar scale commonly used to compare sizes of stars and stellar structures.

Is this conversion precise for all applications?

No, the conversion is theoretical and useful mainly for comparative purposes, considering the Sun's radius is an average and light year distances are vast.
