Convert Earth's equatorial radius to Bohr radius
Please provide values below to convert Earth's equatorial radius [R_e] to Bohr radius [a.u.], or Convert Bohr radius to Earth's equatorial radius.
How to Convert Earth's Equatorial Radius to Bohr Radius
1 R_e = 1.20529321153422e+17 a.u.
Example: convert 15 R_e to a.u.:
15 R_e = 15 × 1.20529321153422e+17 a.u. = 1.80793981730134e+18 a.u.

Earth's Equatorial Radius
The Earth's equatorial radius is the distance from the center of the Earth to the equator, approximately 6,378.1 kilometers.
History/Origin
The size and shape of the Earth have been a subject of study since ancient times. Modern measurements are made using satellite geodesy.
Current Use
The Earth's equatorial radius is a fundamental parameter in geodesy, geophysics, and astronomy. It is used in cartography and for defining the shape of the Earth.
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.
