What does the unit Sun's radius represent?

The Sun's radius is the mean radius of the Sun, used as an astronomical unit of length to compare sizes of stars and stellar structures.

Why convert Sun's radius to kilometers?

Converting to kilometers helps express astronomical distances in more familiar units useful for comparisons and educational purposes.

Is the conversion from Sun's radius to kilometers exact?

The conversion uses an average value because the Sun's radius can vary slightly due to solar activity and measurement techniques.
