This video tutorial covers the conversion between customary and metric units. It begins with an introduction to the concept and provides a table of approximate equivalences. The instructor demonstrates how to solve conversion problems using proportions and a calculator, with examples including gallons to liters, miles to kilometers, and kilograms to pounds. The video also includes a real-world example of converting the distance of Mammoth Cave from miles to kilometers. Students are encouraged to practice with a 'U-Try' section, and the lesson concludes with a reminder that these conversions are not expected to be memorized.
