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

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.
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.
Frequently Asked Questions
What is 1 Sun's radius in astronomical unit?
1 Sun's radius (R_s) = 0.00465046726096 astronomical unit (AU, UA).
How do you convert Sun's radius to astronomical unit?
