Liter is a volume unit and kilometer is a distance unit. There are 5,000 meters in 5 kilometers, and 5,000 liters in 5 kiloliters. Kilo means one thousand. Liters measure volume of a liquid (how much Coke do I have?) and meters measure distance (how far do I have before I get a touchdown).

35 liters is equal to 35000 milliliters. This is due to the fact that there are a thousand (1000) milliliters per liter. Therefore one-thousand times thirty-five equals thirty-five thousand milliliters (35X1000=35000).
