The Iranian toman is a superunit of the official currency of Iran, the rial. One toman is equivalent to ten rials. Although the rial is the official currency, Iranians use the toman in everyday life. Originally, the toman consisted of 10,000 dinars. Between 1798 and 1825, the toman was also subdivided into eight rials, each of 1,250 dinars. In 1825, the qiran was introduced, worth 1,000 dinars or one-tenth of a toman.
