Convert Angstrom to Astronomical unit (Å to Astronomical unit)

Angstrom (Å) and Astronomical unit (Astronomical unit) are both units of length. With the conversion form below, you can effortlessly and accurately convert angstrom to astronomical unit. This free online calculator tool makes it simple and easy to perform the conversion from Å unit to the Astronomical unit unit.

Length is the measure of distance in one dimension—the extent of an object from one end to the other, or the distance between two points. The SI base unit is themeter (m), defined since 1983 as the distance light travels in a vacuum in 1/299,792,458 of a second. Common derived units include the kilometer (1 km = 1,000 m) for distances and the centimeter (cm) and millimeter (mm) for everyday measurements. US customary length units include the inch (in), foot (ft), yard (yd), and mile (mi). The nautical mile (1,852 m) is used in aviation and maritime navigation.

Angstrom (symbol: Å) is a non-SI unit of length equal to 1 × 10^-10 meter, or 0.1 nanometer. It is commonly used to express atomic-scale distances, including the sizes of atoms, chemical bond lengths, crystal lattice spacing, and the wavelengths of electromagnetic radiation such as X-rays and ultraviolet light. Although the angstrom is not an official SI unit, it is widely recognized and accepted for use in physics, chemistry, materials science, crystallography, and molecular biology because it provides a convenient scale for describing extremely small lengths.

Angstroms are widely used in atomic physics, spectroscopy, crystallography, nanotechnology, and structural biology. The unit offers a practical alternative to scientific notation when measuring atomic dimensions and molecular structures. This converter follows the internationally accepted relationship of 1 angstrom = 10^-10 meter = 0.1 nanometer = 100 picometers, ensuring accurate and reliable conversion between angstroms and other length units.

The astronomical unit (symbol: AU, au, or ua) is a unit of length defined as exactly 149,597,870,700 meters. It is based on the average distance between the Earth and the Sun and is widely used to express distances within the Solar System. Learn more about the meter and length.

One astronomical unit is equal to 149,597,870,700 meters, 149,597,870.7 kilometers, 92,955,807.27 miles, and 0.0000158125 light-years. It is commonly used in astronomy, astrophysics, planetary science, and space exploration to describe distances between planets, asteroids, and the Sun.
