Converting Between American and Metric Units of Length

This video tutorial covers the conversion of units between American and metric systems, focusing on length. It introduces the unit fraction method, where conversions are performed by multiplying by a fraction with the desired unit in the numerator. The video provides examples of converting meters to feet, inches to centimeters, and kilometers to miles. Additionally, it demonstrates a more complex conversion of speed from miles per hour to kilometers per hour and meters per second. The tutorial emphasizes simplifying units and using conversion tables effectively.
