Convert Earth's distance from sun to a.u. of length
Please provide values below to convert Earth's distance from sun [AU_dist] to a.u. of length [a.u., b], or Convert a.u. of length to Earth's distance from sun.
How to Convert Earth's Distance From Sun to A.u. Of Length
1 AU_dist = 2.82698984097859e+21 a.u., b
Example: convert 15 AU_dist to a.u., b:
15 AU_dist = 15 × 2.82698984097859e+21 a.u., b = 4.24048476146789e+22 a.u., b

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.
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.
