The pous (pl. podes; Greek: πούς, poús) or Greek foot (pl. feet) was a Greek unit of length. It had various subdivisions whose lengths varied by place and over time. 100 podes made up one plethron, 600 podes made up a stade (the Greek furlong) and 5000 made up a milion (the Greek mile). The Greek pous also has long, median and short forms.
The pous spread throughout much of Europe and the Middle East during the Hellenic period preceding and following the conquests of Alexander the Great and remained in use as a Byzantine unit until the Fall of Constantinople in 1453.
