Convert Earth's distance from sun to Bohr radius
Enter a value below to convert Earth's distance from sun [AU_dist] to Bohr radius [a.u.]. Reverse conversion: Convert Bohr radius to Earth's distance from sun.
1 AU_dist = 2.8270e+21 a.u.. To convert Earth's distance from sun to Bohr radius, multiply the value by 2.8270e+21; to go the other way, divide by it (1 a.u. = 3.5373e-22 AU_dist). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Earth's Distance From Sun: Definition and Use
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: Definition and Use
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.
