I learned how to convert units from the SI system to the imperial system and from imperial to SI. In the example given, I am converting 208 inches into meters using unit analysis. Depending on what units you are converting, you may have to go through multiple conversions. For me, I had to convert inches to centimeters and then centimeters to meters. When converting and cancelling out a unit, you need to make sure that unit is on the numerator and then again on the denominator, as you can see in the example.
