Batman (unit)
The batman (Turkish pronunciation: [batˈman]) was a unit of mass used in the Ottoman Empire and among Turkic peoples of the Russian Empire. It has also been recorded as a unit of area in Uyghur-speaking regions of Central Asia. The name is Turkic (Ottoman Turkish: بطمان, romanized: baṭmān; Chagatay: bātmān), but was also sometimes used for the equivalent unit in Persia (من man). The equivalent unit in British India was anglicized as the maund (Bengali: মন and Hindustani: من). The value of the batman (or maund) varied considerably from place to place.
