What this unit was
Attic pous is modelled here as a length standard of the Greek tradition, associated with Attica during Classical to Hellenistic representative. The converter represents one pous as 0.2957 m; its basis is architecture-inferred. The matrix carries an indicative uncertainty of ± 0.001 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 Smith Dictionary Mensura. Its record is classified as medium confidence and uses the stated basis rather than an assumed culture-wide constant.

What the unit meant
Greek metrology was regional. The Attic pous is reconstructed through architectural dimensions, written relationships, and comparisons among standards. A representative near 295.7 mm has a long scholarly history, yet individual monuments do not always yield tidy integer modules. Design, construction tolerance, later damage, measurement selection, and competing foot hypotheses all influence the result.
How this site models it
The v1 matrix pairs the 295.7 mm representative with a 177.42 m stadion calculated as six hundred feet and cross-checks it against recent work identifying an itinerary cluster near 177 m. The page does not claim that every Athenian distance or every dimension of the Parthenon follows that exact value. It offers a transparent hypothesis to test.
What not to infer
Finding a near-integer quotient after trying several candidate feet is not conclusive evidence. The more dimensions, standards, and rounding choices tested, the easier it becomes to find an attractive match. A serious argument states the candidate in advance, uses multiple independent dimensions, and reports failures as readily as successes.
The Parthenon and Acropolis: the case-study lens
The most famous test case for Greek architectural proportion is also a warning against forcing a preferred foot or golden ratio onto every dimension. This pairing is a historically bounded investigation, not a claim that one decimal unlocks the whole building.
