What is the Sun's radius used for?

The Sun's radius serves as an astronomical unit of length for expressing stellar sizes and is commonly used when reporting and comparing star dimensions.

What distances does the femtometer measure?

A femtometer measures extremely small lengths, such as the sizes of atomic nuclei and scales relevant in nuclear and particle physics.

Why convert from the Sun's radius to femtometers?

Converting allows comparisons and modeling across astronomy and nuclear physics by bridging very large stellar scales with very small nuclear distances.
