The ancient Greek equivalent was the square plethron, which served as the Greeks' form of the acre. It was originally defined as the distance plowed by a team of oxen in a day but was nominally standardized as the area enclosed by a square 100 Greek feet (pous) to a side. It was the size of a Greek wrestling square.
The Byzantine or Morean stremma continued to vary depending on the period and the quality of the land, but usually enclosed an area between 900–1,900 m2 (9,700–20,500 sq ft). It was originally also known as the "plethron" but this was eventually replaced by "stremma", derived from the verb for "turning" the ground with a Byzantine plow.
The Ottoman stremma, often called the Turkish stremma, is the Greek (and occasionally English) name for the dunam, which in turn is probably derived from the Byzantine unit. Again, this varied by region: some values include 1,270 m2 (13,700 sq ft), and 1,600 m2.
