Convert astronomical unit to Sun's radius
Enter a value below to convert astronomical unit [AU, UA] to Sun's radius [R_s]. Reverse conversion: 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: Definition and Use
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: Definition and Use
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.
