How accurate are the conversion results on ConvertUnits?

The converter uses standard astronomical unit definitions and provides results to several decimal places, but users should verify critical measurements against authoritative sources due to possible rounding.

Can I convert from kilometers back to astronomical units?

Yes, the tool supports reverse conversions; entering a value in kilometers and selecting astronomical units as the target will return the equivalent AU value.

What other length units can I convert with this tool?

The site offers a comprehensive list including meters, miles, feet, inches, parsecs, light‑years, and many other metric and imperial units, all accessible from the same input form.

Is there a limit on the size of numbers I can convert?

The form accepts numerical input without a stated maximum, but extremely large or small values may display in scientific notation, and very large numbers can trigger rounding artifacts.
