Unit Definition (jitro, joch, jutro)
The joch is a traditional unit of area in German speaking countries, especially in Austria. One joch is the area of a square 40 klafters (about 83 yards) on a side. This comes to 0.5755 hectare or about 1.422 acres. The plural is joche. Joch is also the word for a yoke in German, so this unit represents an area that could be plowed in a day by a yoke of oxen. In what is now the Czech Republic this unit was known as the jitro; in Croatia it is the jutro.
