What is a link (US survey) unit used for?

It is a historical linear unit equal to 1/100 of a Gunter's chain, mainly used in US land surveying for measuring subdivisions and cadastral records.

Why convert from link (US survey) to perch?

Because perch is another traditional land measurement unit, converting helps interpret historical records that use different units for clarity and comparison.

Are the link and perch units still used today?

These units are mostly obsolete but remain important when working with historical or legacy land survey and property documents.
