Please provide values below to convert Bohr radius [a.u.] to Earth's polar radius [R_p], or Convert Earth's polar radius to Bohr radius.
How to Convert Bohr Radius to Earth's Polar Radius
1 a.u. = 8.32464733450444e-18 R_p
Example: convert 15 a.u. to R_p:
15 a.u. = 15 × 8.32464733450444e-18 R_p = 1.24869710017567e-16 R_p
Bohr Radius to Earth's Polar Radius Conversion Table
| Bohr radius | Earth's polar radius |

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.
Earth's Polar Radius
The Earth's polar radius is the distance from the center of the Earth to the North or South Pole, approximately 6,356.8 kilometers.
History/Origin
The fact that the Earth is an oblate spheroid, flattened at the poles, has been known since the 18th century. Modern measurements are made with high precision.
Current Use
The Earth's polar radius is a key parameter in geodesy and is used to define the Earth's shape and gravitational field.
