The New Taiwan dollar (code: TWD; symbol: NT$ or $, also abbreviated as NT or NTD), or the Taiwan dollar, is the official currency of the Republic of China (Taiwan). Usually, the $ sign precedes the amount, but NT$ is used to distinguish from other currencies named dollar. The New Taiwan dollar has been the currency of the island of Taiwan since 1949, when it replaced the old Taiwan dollar, at a rate of 40,000 old dollars per one new dollar. The base unit of the New Taiwan dollar is called a yuan (圓), subdivided into ten jiao (角) or 100 fen (分), although in practice neither jiao nor fen are used.
There are a variety of alternative names for the units in Taiwan. The unit of the dollar is typically informally written with the simpler equivalent character as 元, except when writing it for legal transactions such as at the bank, when it has to be written as the homophonous 圓. Colloquially, the currency unit is called both 元 (yuán, literally "round") and 塊 (kuài, literally "piece") in Mandarin, 箍 (kho͘, literally "hoop") in Hokkien, and 銀 (ngiùn, literally "silver") in Hakka.
