How many kilometers are in one astronomical unit?

One astronomical unit equals 149,597,870.691 kilometers, as defined by the standard conversion factor used on the UnitConverters.net page.

Can I convert kilometers back to astronomical units using this tool?

Yes, the page includes the reverse conversion factor: one kilometer equals approximately 6.6845871226706E-9 astronomical units, allowing bidirectional conversion.

Is there a limit to the size of the astronomical unit value I can convert?

The converter displays a conversion table up to 1000 AU, but the underlying calculation can handle larger values; very large numbers may be truncated or displayed in scientific notation depending on the interface.

Does the tool allow me to adjust the number of decimal places in the result?

The interface provides a precision selection option, enabling users to control the number of decimal places shown in the converted kilometer value.

About this tool

What Astronomical Units to Kilometers Converter does

The Astronomical Units to Kilometers Converter on UnitConverters.net provides a straightforward way to translate distances between AU and kilometers. Users enter a value in astronomical units and can select the desired precision level to ensure accurate results. The tool outputs the equivalent distance in kilometers, supported by a detailed conversion table that lists common values from 0.01 AU up to 1000 AU, and includes the mathematical relationship: one AU equals 149,597,870.691 kilometers. This makes it easy to grasp the scale of interplanetary distances in more familiar metric terms. In addition to the basic converter, the page offers links to convert astronomical units to other length units such as meters, miles, and light-years, expanding its utility beyond a single conversion. A worked example demonstrates the process, showing how to multiply the AU value by the fixed conversion factor to obtain the kilometer result.
