What is an astronomical unit?

An astronomical unit (AU, UA) is a unit of length exactly equal to 149,597,870,700 meters, historically representing the average distance from Earth to the Sun, used to express distances within the Solar System.

What is a league and how is it used?

A league is a historical unit of length used for land and sea distances, often defined as 3 statute miles or 3 nautical miles, appearing in older navigation records and literature.

Why convert astronomical units to leagues?

Converting to leagues allows expressing vast Solar System distances in traditional units for historical analysis, navigation research, or literary contexts.

Browser-based and straightforward to use for quick calculations.

Examples

1 AU equals 30,985,269.089144 leagues.
0.5 AU equals 15,492,634.544572 leagues.

Common Use Cases

Expressing planetary orbital distances and semi-major axes within the Solar System.
Analyzing spacecraft trajectories and mission planning distances.
Interpreting historical nautical charts or land surveys using leagues.
Comparing traditional distance units in literature and historical texts.

Tips & Best Practices

Verify you select the correct initial and target units before converting.
Use the conversion for comparative or historical reference rather than precise scientific measurements.
Understand that leagues represent varying historical values but use the common league definition here.
Refer to examples for quick validation of conversion results.

Limitations

The league is a non-SI unit with values that differ regionally and historically.
Conversion assumes the most common league definition, which may not fit all contexts.
Very large conversion results make leagues unsuitable for scientific accuracy in astronomy.
