Indonesian Rupiah
The rupiah (IDR) is the currency that is used in Indonesia. The origins of the rupiah go back to a Hindu word for silver, rupiya. The rupiah is also used as the official currency of many of the islands that surround Indonesia, such as the Riau islands and parts of New Guinea. The rupiah has always been a currency that has experienced high rates of inflation, and a rupiah today equals about 0.000075 USD. The rupiah wasn’t used as official tender until 1945, after the Japanese occupation of the country.
