Unit Conversion and Dimensional Analysis

This video tutorial demonstrates how to convert units using dimensional analysis, specifically converting 10.0 km per liter to miles per gallon. It begins by identifying equivalent statements necessary for conversion, such as 1 mile equals 1.609 km and 1 gallon equals 3.785 liters. The tutorial explains the importance of using the correct gallon type and setting up conversion factors to cancel out units. The conversion process is detailed, leading to a final answer of 23.5 miles per gallon, rounded to three significant figures.
