What is the Sun's radius used for?

The Sun's radius serves as a standard length unit in astronomy to compare sizes of stars and stellar structures.

How many meters are in one Sun's radius?

One Sun's radius is equal to 696,000,000 meters based on the defined average value.

Why convert Sun's radius to meters?

Converting to meters enables consistent use of the SI unit system for scientific analysis, engineering, and space-related calculations.
