RUB meaning in Regional ?

The Russian ruble or rouble (Russian: рубль rublʹ; symbol: ₽, руб; code: RUB) is the currency of the Russian Federation, the two partially recognised republics of Abkhazia and South Ossetia and the two unrecognised republics of Donetsk and Luhansk. The ruble is subdivided into 100 kopeks (sometimes written as kopecks or copecks; Russian: копе́йка kopeyka, plural: копе́йки kopeyki).

The ruble was the currency of the Russian Empire and of the Soviet Union (as the Soviet ruble). However, today only Russia, Belarus and Transnistria use currencies with the same name. The ruble was the first currency in Europe to be decimalised, in 1704, when the ruble became equal to 100 kopeks.

In September 1993, the Soviet ruble (code: SUR) was replaced with the Russian ruble (code: RUR) at the rate 1 SUR = 1 RUR. In 1998, preceding the financial crisis, the Russian ruble was redenominated with the new code "RUB" and was exchanged at the rate of 1,000 RUR = 1 RUB.
