Iranian Toman

The toman (تومان in Persian, pronounced [tomæn]), is a superunit of the official currency, rial. Toman derived from a Turkic word meaning ten thousand (see tumen), was the currency of Iran until 1932. It was divided into 10,000 dinar. Between 1798 and 1825, the toman was also subdivided into 8 rial, each of 1250 dinar. In 1825, the qiran was introduced, worth 1000 dinar or one tenth of a toman.

In 1932, the rial replaced the toman at a rate of 1 toman = 10 rials (i.e., 1 rial = 1 qiran). Although the rial is the official currency of Iran, many Iranians employ the term toman in everyday transactions for an amount of 10 rials. In unofficial circumstances, a toman may also refer to either 1,000 tomans or 1,000,000 tomans. The order of the magnitude of the amount would be considered to be apparent from the context.
