Buyer's guide

How to choose a astronomical distance converter

When picking a tool for astronomical distance conversion, first decide which units matter most: if you are working with everyday lengths like inches, look for a converter that specifically handles that unit, otherwise a general astronomical unit tool will suffice. Check whether the interface offers an input form for your own numbers or only a static conversion table, and be aware that some sites include advertisements that may affect usability.

Questions

Astronomical Distance Converter FAQ

How many inches are in one astronomical unit?
One astronomical unit equals 5,889,679,948,464.6 inches, based on the standard AU-to-inch conversion used by the calculators.
Can these tools convert light-years to astronomical units?
