What is a square mile (US survey)?

It is an area unit based on a square with sides one US survey mile long, used primarily in United States land surveying and cadastral records.

What does a square hectometer represent?

A square hectometer equals the area of a square 100 meters on each side, which is the same as one hectare and commonly used in agricultural and land measurements.

Why convert from square miles (US survey) to square hectometers?

Conversion helps standardize land area measurements into internationally recognized SI units for agriculture, surveying, and engineering, especially to integrate legacy US data with metric systems.
