Understand the price

The rial-toman exchange rate is a frequent source of misunderstanding and dissatisfaction among travelers. The rial is the national currency, yet Iranians exclusively communicate in toman. To compute, subtract one zero from the rial value (for example, 100,000 rial Equals 10,000 toman). However, things can become more difficult. Some cafés, restaurants, and retailers charge in the rial, while others charge in toman. The salesperson will almost certainly give you the price in toman, and in that case, they will frequently use, for example, 20 toman to imply 20,000 toman (200,000 rial). When in doubt, request the price in rial (or dollars or euros).

Iranian toman is another popular money among Iranians. Toman is not an official Iranian currency, but it is so deeply embedded in Iranian society that most internet retailers price their items in toman rather than rial. Official systems, such as banks and exchange bureaus, however, are entirely in rial.
