Greek units in the context of "Byzantine units of measurement"

The pous (pl. podes; Ancient Greek: πούς, poús) or Greek foot (pl. feet) was a Greek unit of length of approximately 300mm or 12 inches. 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.

Schoenus (Latin: schœnus; Ancient Greek: σχοίνος, schoinos, lit. "rush rope"; Ancient Egyptian: i͗trw, lit. "river-measure") was an ancient Egyptian, Greek and Roman unit of length and area based on the knotted cords first used in Egyptian surveying.

Plethron (Ancient Greek: πλέθρον, plural plethra) is an ancient Greek unit of measurement equal to 97 to 100 Greek feet (ποῦς, pous; c. 30 centimeters), although the measures for plethra may have varied from polis to polis. This was roughly the width of a typical ancient Greek athletic running-track.

A plethron could also be used as a unit of measured area, and reference to the unit in defining the size of a wrestling area is made by Libanius. A square plethron of c. 30 by 30 meters was used as the standard dimensions of a Greek wrestling square, since such competitions were held within the racing track in ancient Greece. In other connotations, it functioned as the Greek acre, and varied in size to accommodate the amount of land a team of oxen could plow in a day.
