According to the most popular version, the word ruble is derived from the Russian verb ÑÑÐ±Ð¸ÌÑÑ (rubit'), meaning to chop, to cut, to hack, as ruble was considered as a cutout piece (a quarter) of a silver Gryvna. A popular theory deriving word ruble from rupee is probably not correct.he ruble is subdivided into 100 kopeks (sometimes written as kopecks or copecks; Russian: ÐºÐ¾Ð¿ÐµÌÐ¹ÐºÐ°, kopeyka; plural: ÐºÐ¾Ð¿ÐµÌÐ¹ÐºÐ¸, 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).
