Convert a.u. of length to Earth's distance from sun
Please provide values below to convert a.u. of length [a.u., b] to Earth's distance from sun [AU_dist], or Convert Earth's distance from sun to a.u. of length.
How to Convert A.u. Of Length to Earth's Distance From Sun
1 a.u., b = 3.53733142406284e-22 AU_dist
Example: convert 15 a.u., b to AU_dist:
15 a.u., b = 15 × 3.53733142406284e-22 AU_dist = 5.30599713609426e-21 AU_dist

A.u. Of Length
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.
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.
