What is the US survey inch?

It is a legacy unit of length equal to 1/12 of the US survey foot, defined exactly as 100/3937 metres, used historically for surveying and mapping in the U.S.

What applications require converting to micrometers?

Micrometers are used for measuring dimensions at the microscale, such as sizes of cells, thickness of films, and components in microsystems.

Can this conversion be used for modern international measurements?

No, the US survey inch differs slightly from the international inch, so this conversion mainly applies to legacy data and specific engineering uses.
