What is a square kilometer used for?

A square kilometer quantifies large two-dimensional areas such as land, water bodies, or large parcels used in geography and urban planning.

Where is the square foot (US survey) unit applied?

It is mainly used in U.S. land surveying, cadastral mapping, and legal property descriptions where the survey-foot standard is required.

Is the survey foot the same as the international foot?

No, the survey foot is slightly different from the international foot, leading to differences in the corresponding square foot measurement.
