This worksheet was about dimensional analysis. This is the method to create ratios to convert from one unit to another. I did this last year, but I did lose my ability to do this a little. It was good practice and it is an important skill to have because of our unit system. We, as Americans, do not use the metric system which forces us to have to convert all our measurements into the metric system, which is what scientists use. The only part of the worksheet that I was a little confused on was converting a volume unit until a measurement unit^3. For example, converting liters to cm^3. I did learn how to do this, and it was because of the help I received from Jake and also past worksheets.
