Why is the mile called the US survey mile?

The US survey mile is a historical unit based on exactly 5,280 US survey feet defined to maintain consistency with older surveying and mapping data in the United States.

What is an astronomical unit used for?

An astronomical unit is used to express large space distances within the Solar System, such as planetary orbits and spacecraft trajectories, to avoid very large meter values.

Can I use this converter for modern mile measurements?

This converter specifically uses the US survey mile definition; modern international mile measurements differ slightly and may require different conversions.

Tips & Best Practices

Ensure you understand the historical basis of mile (US survey) in your data for accurate conversion.
Use this converter primarily when bridging terrestrial maps and astronomical scales.
Remember astronomical units represent very large distances, so converted values will be very small decimals.
Consider using meters or kilometers alongside when extreme precision is required.

Limitations

Mile (US survey) differs from modern international mile definitions, which may affect equivalence.
Astronomical units cover vast distances making resulting values very small decimals.
Conversions are mainly useful in contexts involving both unit systems; otherwise, metric units may be simpler.
High precision is required due to scale differences in the units.
