They are metric units of measuring distance. A millimeter is about the thickness of a grain of rice. A centimeter is 10 times longer (roughly the width of your finger). A meter is 100 times the length of a centimer (roughly half the height of a door). A kilometer is 1000 meters. I think a kilometer is around half a mile. This should give you a better grasp on the size of each.
