Unit Information

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.

Light Year
/lʌɪt jɪə,jəː/

Symbol: ly
Unit System: Astronomical System of Units

What is the Light Year?

The light year is a unit of length in the Astronomical system of units. It uses the symbol ly.

Often confused with a unit of time as it contains the word "year", it is actually defined by the International Astronomical Union (IAU) as the amount of distance that light travels in a vacuum in one Julian year (365.25 days).

Using the speed of light (299,792,458 m/s or 'c') and the Julian year (as apposed to the Gregorian year which is 365.2425 days), we can equivalate 1 light year as 9,460,730,472,580,800 metres or ≈ 9.46 trillion kilometres.
