The ruble or rouble (in Russian: рубль rubl' ) is a unit of currency. It is currently the currency unit of Belarus, Russia, and Transnistria, and was the currency unit of several other countries, notably countries influenced by Russia and the Soviet Union. One ruble is divided into 100 kopeks or copecks.

According to one version, the word "ruble" is derived from the Russian verb рубить, rubit, i.e., to chop. Historically, "ruble" was a piece of a certain weight chopped off a silver ingot (grivna), hence the name. Another more convincing version is that the name comes from the Russian noun рубец, rubets, i.e., the seam that is left around the coin after casting: silver was added to the cast in two steps. Therefore the word ruble means "a cast with a seam".
In Russian, a folk name for "ruble", tselkovy (целковый, wholesome), is known, which is a shortening of the "целковый рубль" ("tselkovyi ruble"), i.e. a wholesome, uncut ruble.
The word kopek, kopeck, copeck or kopeyka (in Russian: копейка, kopeyka) derives from the Russian kop'yo (копьё) – a spear. The first kopek coins, minted at Novgorod and Pskov from about 1535 onwards, show a horseman with a spear. From the 1540s onwards the horseman bears a crown, and doubtless the intention was to represent Ivan the Terrible who was Grand Prince of all Russia until 1547 and Tsar thereafter.
It is worth noting that Russia was the first country in the world to introduce a decimal monetary system (1704) where one ruble was equal to 100 kopeks.
Soviet banknotes had their value printed in the languages of 15 republics of the Soviet Union.
