What this unit was
Attic stadion is modelled here as a length standard of the Greek tradition, associated with Attica during Classical to Hellenistic representative. The converter represents one stadion as 177.42 m; its basis is derived-from-pous. The matrix carries an indicative uncertainty of ± 0.6 m.
Within that setting, the unit belonged to a working system for survey, building, travel, and the organisation of built 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.
Evidence of use and sources
The working value is traceable to Archive for History of Exact Sciences 2025. Its record is classified as medium confidence and uses the stated basis rather than an assumed culture-wide constant.
