Convert astronomical unit to a.u. of length
Enter a value below to convert astronomical unit [AU, UA] to a.u. of length [a.u., b]. Reverse conversion: Convert a.u. of length to astronomical unit.
1 AU, UA = 2.8270e+21 a.u., b. To convert astronomical unit to a.u. of length, multiply the value by 2.8270e+21; to go the other way, divide by it (1 a.u., b = 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.
A.u. Of Length: Definition and Use
The atomic unit of length, also known as the Bohr radius (a₀), is 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 where the electron orbits the nucleus at specific distances. The Bohr radius is the most probable distance between the proton and electron in a hydrogen atom in its ground state.
Current Use
The atomic unit of length is used in atomic physics to simplify calculations and equations.
