What is the US survey inch?

It is a legacy unit of length used for surveying in the U.S., defined as exactly 100/3937 metres.

Why convert from inch (US survey) to kilometer?

To translate historical surveying measurements into metric distances suitable for modern mapping and engineering.

Can this tool be used for modern engineering units?

No, for current large-scale engineering, modern international foot and inch units with metric are preferred.
