Convert Earth's distance from sun to angstrom
Please provide values below to convert Earth's distance from sun [AU_dist] to angstrom [A], or Convert angstrom to Earth's distance from sun.
How to Convert Earth's Distance From Sun to Angstrom
1 AU_dist = 1.495978707e+21 A
Example: convert 15 AU_dist to A:
15 AU_dist = 15 × 1.495978707e+21 A = 2.2439680605e+22 A

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.
Angstrom
The angstrom is a unit of length equal to 10⁻¹⁰ meters. It is not an SI unit.
History/Origin
In 1868, Swedish physicist Anders Jonas Ångström created a chart of the spectrum of sunlight in which he expressed the wavelengths in multiples of one ten-millionth of a millimeter. The unit was named after him.
Current Use
The angstrom is used to express the sizes of atoms, molecules, and the wavelengths of electromagnetic radiation, particularly in the fields of chemistry, spectroscopy, and crystallography.
