Astronomical Distance Conversion

In Space, distances are vast, therefore larger units are required to capture these immense lengths/distances. These units include the Astromical Units, Parsec, Lightyears and Angstrom.

An astronomical unit (au) is a unit of length equal to about 149,597,870.7 kilometres (or 92,955,807.3 miles), approximately the mean Earth-Sun distance.

A light year is defined as the distance that light would travel in one year - just under 1016 metres.

One Parsec is about 3.26 light-years or (3.1x1013) kilometres
