What is the US survey inch used for?

The US survey inch was used in historical U.S. geodetic control, cadastral surveys, and mapping before being largely replaced by the international inch.

What does a span (cloth) measure?

A span (cloth) is a traditional length unit based on the distance between the thumb and little finger of an outstretched hand, commonly about 9 inches.

Can this conversion be used for contemporary measurements?

This conversion is mainly useful for interpreting historical or textile-related measurements, as both units have limited use in modern standard measurements.
