You do NOT need Dimensional Analysis, a topic in applied algebra for developing complex formulae, simply to convert between the multiple steps in any one measurement in the Metric System. That's the second answer I have seen so far trying to confuse students by citing advanced mathematics - and then incorrectly.
All you need to know for the Metric System is that the units ascend or descend in multiples or divisions of 10, and the names for those X10 steps.
