The singular hides the problem
Modern reference tables often compress the Greek pous into one convenient number. Excavated stadia and architectural studies resist that simplification. A foot around 296 mm and one above 320 mm create meaningfully different reconstructions.
A stadion makes variation visible
Six hundred feet sounds like a definition, yet six hundred of which regional foot? Olympia approaches 192 m while an Attic itinerary family clusters near 177 m. The count survives; the realised length changes.
Designing the honest interface
The converter repeats the unit name but foregrounds region and period. That is less tidy and more useful. Friction prevents anachronism. A good historical tool should make the important choice unavoidable rather than hide it behind a generic default.
