stremma

Etymology
From, referring to the turning of the soil.

Noun

 * 1) A Greek unit of land area, now equal to a decare (1,000 m²) but  previously 10,000 square Greek feet.
 * 2)  The dunam, the Turkish unit of land area derived from the Greek unit.

Usage notes
The standard was that the stremma was equal to a square formed by sides of 100 Greek feet, but in practice this was adjusted at a provincial or local level for differences in land quality to accommodate the term's colloquial sense of denoting the area able to be plowed in a day of work, a usage equivalent to the English acre.

Abbreviated in English as str.
