Russian ruble

The ruble or rouble (, , plural , rubli; see note on English spelling) (sign: ₽; code: RUB) is the currency of Russia and the two partially recognized republics of Abkhazia and South Ossetia. Originally, the ruble was the currency of the Russian Empire and the Soviet Union before its dissolution. Belarus and Transnistria use currencies with the same name. The ruble is subdivided into 100 kopeks (sometimes written as kopecks or copecks; , kopeyka; plural: , kopeyki). The ISO 4217 code is RUB or 643; the former code, RUR or 810, refers to the Russian ruble before the 1998 redenomination (1 RUB = 1,000 RUR). The Russian ruble is the world's first decimal currency, being decimalised in 1704 when the ruble became legally equal to 100 kopeks.
