Unit Information

Astronomical Unit
/astrəˈnɒmɪk(ə)l ˈjuːnɪt/

Symbol: AU
Unit System: Astronomical system of units

What is the Astronomical Unit?

The astronomical unit is a unit of length and is used in the Astronomical system of units and denoted by the symbol au.

It represents the average distance between the Earth and the Sun which is approximately 150 million kilometres (or 93 million miles).

It's used mostly to express distances within our Solar System.

Angstrom
/ˈaŋstrəm/

Symbol: Å
Unit System: Non-SI Metric

What is the Angstrom?

The angstrom (or ångström) is a unit of length and is a non-SI but metric accepted unit with the symbol Å.

It is equal in length to one ten-billionth of a metre or 0.1 nanometres (0.1nm).

It is approximately the size of an atom and is mostly used to measure very small distances for example wavelengths of light.
