Convert astronomical unit to Sun's radius
Please provide values below to convert astronomical unit [AU, UA] to Sun's radius [R_s], or Convert Sun's radius to astronomical unit.
1 AU, UA = 215.032155671 R_s. To convert astronomical unit to Sun's radius, multiply the value by 215.032155671; to go the other way, divide by it (1 R_s = 0.00465046726096 AU, UA). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Astronomical Unit
The astronomical unit is a unit of length, now defined as exactly 149,597,870,700 meters. It is approximately the average distance between the Earth and the Sun.
History/Origin
Historically, the astronomical unit was the mean Earth-Sun distance. In 2012, the International Astronomical Union (IAU) redefined it as a fixed constant.
Current Use
The astronomical unit is used primarily for measuring distances within the Solar System or around other stars.
Sun's Radius
The Sun's radius is the distance from the center of the Sun to its surface, approximately 695,700 kilometers.
History/Origin
The size of the Sun has been measured with increasing accuracy over centuries of astronomical observation.
Current Use
The Sun's radius is a fundamental property of the Sun and is used in astrophysics to model its structure and evolution.
