What is the foot (US survey) used for?

It is historically used in U.S. land surveying, mapping, specifying property boundaries, and referencing engineering project dimensions linked to older survey records.

Why convert feet to Earth's equatorial radius?

Converting feet to Earth's equatorial radius allows integration of local survey measurements with global geodetic reference systems important in mapping, aerospace, and Earth science.

What should I be aware of regarding unit differences?

Different foot definitions exist, such as the international foot, so ensuring consistent units is important for precise conversions.
