Uqiyyah
The Uqiyyah, sometimes spelled Awqiyyah, is the name for a historical unit of weight that varies between regions, as listed below. It corresponds to the historical unit ounce and was defined in Iraq as the 12th part of a ratl or in parts of Egypt as an 8th of a ratl. As the ratl varied so did the uqiyyah as its part.
Egypt: 37g
Aleppo: 320g
Beirut: 213.39g
Jerusalem: 240g
Malta: ~26.46 g
The same unit, pronounced uqqa or okka in Turkish, was used in the Ottoman Empire until the early 20th century. The standard Istanbul okka equaled 128.3 g.
