About this rate

An exchange rate is the ratio between two currencies. IRR/STN on this page means how much Sao Tome and Principe Dobra one unit of Iranian Rial buys; the inverse rate is the same relationship read the other way.

The rates here are daily reference mid-rates. They are good for estimating an amount or reading a trend, but they are not any institution's dealing price. Banks, bureaux de change and payment providers all add a spread and fees on top of the mid-rate, so what you actually receive is usually less than the figure computed here.

Every pair is derived from each currency's rate against the US dollar (IRR/STN = USD/STN ÷ USD/IRR), so cross rates between two thinly traded currencies carry more error than the major pairs.

FAQ

How do I convert one hundred units of a foreign currency?
Multiply the original amount by the exchange rate in the intended direction. If an illustrative rate is 7 target units for 1 source unit, then 100 source units convert mathematically to 700 target units. Those numbers are examples, not live quotations. The page's reference conversion excludes provider spreads and fees and does not establish an executable trading price, so check a provider's actual terms before using it for a transaction.
How are forward and reverse currency exchange rates related?
For the same reference quote, the reverse exchange rate is the reciprocal of the forward rate. An illustrative forward rate of 2 therefore gives a reverse rate of 0.5. Real providers can quote separate buying and selling rates, with spreads and charges. Do not use the page's reciprocal relationship alone to predict transaction proceeds, especially when comparing offers that use different quote times or settlement arrangements.
Does the online currency conversion automatically include exchange fees?
This tool converts amounts using reference rates without automatically subtracting a provider's exchange fees. If the computed amount is 100 units and a separate fixed charge is 2 units, account for that charge yourself when comparing proceeds. These are illustrative numbers. Actual fee rules, spreads, and settlement timing can differ, so use the specific provider's quote to assess a transaction rather than assuming the displayed conversion is a final payout.
