Dimensional Analysis is a basic unit conversion most often used in Chemistry. The main goal of Dimensional Analysis is to cancel out the units that you do not need and keep the units that you are converting to.
Here are some videos that may make it easier to understand.
Dimensional Analysis Explained in comparison to Unit Conversion
"King Henry" Killed Math
Many teachers use the following letters to help their students convert from metric unit to another
K H D U D C M
Teachers have students repeat the phrase "King Henry Dies Unexpectedly Drinking Chocolate Milk"
Associating these units to non-math terms allows us to get our students over the hurdle of converting from one unit to another, but it doesn't explain the mathematics behind the conversion process. I really like how this is explained in the following video. Replace the prefix with the number that it represents and make both sides equal.
I plan on explaining Dimensional Analysis further in future posts.
