Converting in the Metric System with Dimensional Analysis

This video tutorial covers dimensional analysis, focusing on converting units using the concept of multiplying by a fraction equal to one, known as the unit giant one. It provides step-by-step examples of converting between different units, such as kilometers to meters, meters to centimeters, and grams to milligrams. The tutorial also includes an advanced example of converting kilometers to centimeters, emphasizing the importance of understanding unit relationships and cancellation.
