Understanding Dimensional Analysis

The video tutorial explains how to convert a speed of 17 cm per minute on a bicycle to meters per hour using dimensional analysis. It involves setting up the conversion by placing centimeters and meters in the correct positions to cancel units, and then converting minutes to hours. The final calculation results in a speed of 10.2 meters per hour. The tutorial emphasizes understanding unit conversions and dimensional analysis.
