Convert Earth's distance from sun to Bohr radius
Please provide values below to convert Earth's distance from sun [AU_dist] to Bohr radius [a.u.], or Convert Bohr radius to Earth's distance from sun.
How to Convert Earth's Distance From Sun to Bohr Radius
1 AU_dist = 2.82699004450178e+21 a.u.
Example: convert 15 AU_dist to a.u.:
15 AU_dist = 15 × 2.82699004450178e+21 a.u. = 4.24048506675267e+22 a.u.

Earth's Distance From Sun
The Earth's distance from the Sun varies throughout the year. The average distance is defined as one astronomical unit (AU), which is about 149.6 million kilometers.
History/Origin
The measurement of the Earth-Sun distance has a long history, with early estimates made by ancient Greek astronomers. Modern measurements are highly precise.
Current Use
The Earth-Sun distance is a fundamental unit in astronomy and is used to measure distances within the solar system.
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.
