An anna was a currency unit formerly used in British India, equal to 1/16 of a rupee. It was subdivided into four pices or twelve pies. When the rupee was decimalised and subdivided into 100 (new) paise, one anna was therefore equivalent to 6+1/4 paise. The anna was demonetised as a currency unit when India decimalised its currency in 1957, followed by Pakistan in 1961. It was replaced by the 5-paise coin, which was itself discontinued in 1994 and demonetised in 2011. The term anna is frequently used to express a fraction of 1⁄16.
