Understanding Measurement Units

The video tutorial explains how to measure the width of a rectangle using two different units: paper clips and centimeters. It demonstrates counting paper clips to determine the width and then using a ruler to measure in centimeters. The tutorial highlights the difference in measurement units, showing that more paper clips are needed than centimeters, indicating that paper clips are a smaller unit. The video concludes by comparing the two units and explaining why centimeters are a larger unit of measurement.
