The ruble or rouble (code: RUB) is the currency of the Russian Federation and the two partially recognized republics of Abkhazia and South Ossetia. Formerly, the ruble was also the currency of the Russian Empire and the Soviet Union before their dissolution. Belarus and Transnistria use currencies with the same name. The ruble is subdivided into 100 kopeks (sometimes transliterated kopecks, or copecks; Russian: копейка, kopéyka; plural: копейки, kopéyki). 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 = 1000 RUR).
Currently there is no official symbol for the ruble, though the abbreviation руб. is in wide use. Various symbols have been suggested as possibilities, including "РР" (Cyrillic for "RR"), an "R" with two horizontal strokes across the top (similar to the Philippine peso sign), ₱, a "Р" with one horizontal strike.
