What is the inch (US survey) used for?

It is a legacy surveying unit used historically in U.S. geodetic control, cadastral surveys, and mapping.

What does Earth's equatorial radius represent?

It is the distance from Earth's center to the equator along the equatorial plane, used as a reference in geodesy and aerospace.

Why is careful conversion important between these units?

Because the conversion factor is extremely small, precision is crucial to avoid errors in calculations.
