What is a chain (US survey) used for?

It is a traditional length unit used historically in U.S. land surveying and cadastral work, equal to 66 US survey feet.

Where is the mil unit commonly applied?

Mil is used primarily in U.S. manufacturing and engineering to specify small thicknesses, clearances, and tolerances.

Why convert from chain to mil?

To transform large, historical land measurement units into very fine units needed for detailed technical and manufacturing applications.
