What is Earth's equatorial radius used for?

It is used for defining reference ellipsoids, map projections, calculating satellite orbits, and converting between geodetic and geocentric coordinates in fields such as geodesy, cartography, and aerospace engineering.

Why is the link (US survey) unit important?

It serves as a small subdivision for linear measurements in US land surveying, particularly useful for interpreting historic cadastral records and legacy survey data.

Can this converter handle international foot units?

No, since the US survey link is based on US survey feet, differences between this and international feet should be considered when working across measurement systems.
