Convert astronomical unit to Bohr radius
Enter a value below to convert astronomical unit [AU, UA] to Bohr radius [a.u.]. Reverse conversion: Convert Bohr radius to astronomical unit.
1 AU, UA = 2.8270e+21 a.u.. To convert astronomical unit 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, UA). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Astronomical Unit: Definition and Use
The astronomical unit is a unit of length, now defined as exactly 149,597,870,700 meters. It is approximately the average distance between the Earth and the Sun.
History/Origin
Historically, the astronomical unit was the mean Earth-Sun distance. In 2012, the International Astronomical Union (IAU) redefined it as a fixed constant.
Current Use
The astronomical unit is used primarily for measuring distances within the Solar System or around other stars.
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.
