Convert Sun's radius to Bohr radius
Please provide values below to convert Sun's radius [R_s] to Bohr radius [a.u.], or Convert Bohr radius to Sun's radius.
1 R_s = 1.3147e+19 a.u.. To convert Sun's radius to Bohr radius, multiply the value by 1.3147e+19; to go the other way, divide by it (1 a.u. = 7.6064e-20 R_s). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 R_s = 1.3147e+19 a.u.
- 1 a.u. = 7.6064e-20 R_s
- 10 R_s = 1.3147e+20 a.u.
- 100 R_s = 1.3147e+21 a.u.
How to Convert Sun's Radius to Bohr Radius
1 R_s = 1.31468246490215e+19 a.u.
Example: convert 15 R_s to a.u.:
15 R_s = 15 × 1.31468246490215e+19 a.u. = 1.97202369735322e+20 a.u.

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.
Bohr Radius
The Bohr radius is the most probable distance between the proton and the electron in a hydrogen atom in its ground state, approximately 5.29 x 10⁻¹¹ meters.
History/Origin
The Bohr radius is named after Niels Bohr, who proposed a model of the atom in 1913. It is the atomic unit of length.
Current Use
The Bohr radius is a fundamental constant in atomic physics and is used to simplify calculations and equations.
