What kind of money do they use in Russia?

What kind of money do they use in Russia? I heard that stuff is really cheap in Russia, but it takes a ton of money to buy anything. Is that true? If I came to Russia would I be a millionaire?

The Ruble is the official currency of the Russian Federation. There are 100 Kopeks in a ruble.
The current exchange rate is aproximately 25.5 Rubles to one Dollar. That means that 50 Rubles is $2 and 200 Rubles is about $8.

Right now (September 2007) a 2 liter of Coke costs 42 Rubles. A liter of milk costs around 16 Rubles, and a liter of gas is about 20 Rubles.
