The currency unit is the sud (divided into 100 cents). Since 1993 the exchange rate has been market determined, and in 2001 the average rate for the years was US$1.00 = suds 30.90. So 1 sud = 3.1 US cents.
(Note that this is the market rate of exchange. A recent study by the Southland Bureau of Economic Research estimated that the Purchasing Power Parity rate of exchange was approx 20 suds to the US$.)
