In this lesson we will learn how to convert quantities from one unit to another in two steps using dimensional analysis (DA).
Converting changes the units but NOT the type of quantity - so a time can be converted from hours into minutes and then minutes to seconds, but a distance cannot be converted into a time!
The conversion factors will be provided for you in the question.
First, set up a "train tracks" with three columns! ⎯|⎯|⎯|
The given number and unit go in the first column on the top row of your train tracks.
Next, use the first conversion factor provided in the question to fill in the second column, with the units placed so that the original unit will get canceled out!
Repeat this step until you have arrived at your goal unit!
Finally, cancel any units that are on both top and bottom, then multiply any numbers in the top row and divide by any numbers on the bottom row to get your answer!
