Why convert from Sun's radius to petameter?

Converting to petameter allows expressing stellar sizes in a standardized SI unit suitable for comparing extremely large astronomical distances.

What does one petameter represent?

One petameter is an SI unit of length equal to 10^15 metres, used for very large distances often between stars or large interstellar structures.

Is the Sun's radius a fixed measurement?

The Sun's radius represents the mean radius of the Sun and serves as a standard astronomical unit for measuring stellar sizes.
