Russia uses the Metric system, which means that all road signs are in kilometers and speed limits in kilometers per hour. Drinks come by the liter (mostly 0.5 or 0.3) or in hundreds of milliliters (usually 330 ml for a can of soda). The exception is shots of vodka (and other liquors), which are generally served in 50- or 100-gram measures. Food is weighed in grams or kilograms.
There are 10 millimeters in a centimeter, 100 centimeters in a meter and 1,000 meters in a kilometer. There are 1,000 milliliters in a liter and 1,000 grams in a kilogram.
