The stadion (plural stadia, Ancient Greek: στάδιον; latinized as stadium; also anglicized as stade), was an ancient Greek unit of length, consisting of 600 ancient Greek feet (podes). There are a range of varieties or understandings of what a stadion was and is; these have been calculated by various historians, and those calculations have varied dramatically (as did perhaps the use and meaning of the term stadion over time in ancient Greece). Thus, the exact length of one stadion is not universally agreed upon today: historians estimate it at between 150 and 210 m (490 and 690 ft), with perhaps something of a convergence around the 185 metres (607 ft) length of an Attic stade.
