What is a square mile (US survey)?

A square mile (US survey) is an area unit equal to a square with sides of one US survey mile, used primarily in U.S. land surveying and cadastral records.

Why convert square miles (US survey) to square millimeters?

Converting to square millimeters allows precise measurements needed in scientific analysis, engineering, and when integrating legacy land data with modern units.

Is the square millimeter an SI unit?

Yes, the square millimeter (mm²) is an SI-derived unit of area representing a square with sides of one millimeter each.
