The distinctive point
square Attic pous: a value with room for evidence
The distinctive point is the uncertainty, not just the headline magnitude. The matrix carries ± 0.0005914 m² and names the basis as derived-from-representative-attic-pous. That keeps comparison possible without pretending that every specimen, survey, or period produced one perfect constant.

What this unit was
square Attic pous is modelled here as a area standard of the Greek tradition, associated with Athens during Classical Attic representative. The converter represents one pous² as 0.08743849 m²; its basis is derived-from-representative-attic-pous. The matrix carries an indicative uncertainty of ± 0.0005914 m².
Within that setting, the unit belonged to a working system for land assessment, cultivation, taxation, and the description of built or agricultural space. It should be read with its period, locality, and evidential basis attached, not as a universal value shared by every culture using a similar name.
