Area conversion uses squared unit relationships
Area measures two-dimensional surface rather than linear distance. Toolmera converts the selected area through square meters, then shows the target value and all supported equivalents.
This is why a linear value in meters cannot be converted directly into square meters without another dimension.

Land units vs. general surface units
Acres and hectares are common for land, while square feet, square meters and square yards are common for rooms, buildings and smaller surfaces.
The all-unit matrix lets you compare land and construction measurements without changing the source value repeatedly.
