think...cent is the root for one one hundreth. that means that there are 100 centimeters in 1 meter. so to convert from centimeters to meters you simply divide by 100! for millimeters, you divide by 1000, etc... To get back to centimeters or millimeters from meters, you simply multiply by either 100 or 1000. since the question you just asked is probably for homework, i will give the answer, but in binary so it is harder to actually find the answer than just me telling you.
