Ch 31: Concepts of Measurement

About This Chapter

Use this chapter to recall concepts of measurement. Read through the lessons to refresh your memory about how different measurements are used, then take the quizzes to test your knowledge of measurement conversion.

Concepts of Measurement - Chapter Summary

If you need a fast reminder about how to use or convert measurements, this chapter provides you with a clear recap on the topic. Not only will you re-learn some of the most common units of measurement, but you'll also see how they are used as well as formulas for converting between different units of measurement. After you make your way through the lessons in this chapter, you should possess the skills to do the following:

  • Describe the metric system
  • Identify capacity, time, weight, length, and other measurement units
  • Use the unit conversion process for standard units of measurement
  • Find perimeter, volume, area, and surface area
  • Convert back and forth between Celsius and Fahrenheit
  • Explain steps for solving problems related to time
  • Find average and constant rates
  • Solve real-world geometry problems related to measurements

Although this chapter does cover a good amount of information, our instructors have separated the chapter into bite-sized lessons to avoid overloading you with information. Each short, manageable lesson focuses on a single concept. Additionally, each lesson can stand on its own, so you don't have to review every lesson in the chapter if you don't want to. You can skip around and examine the lessons in any order you want, and you can always go back over the lesson materials at any time. Furthermore, since each lesson is so short in duration, you can easily fit in more study time throughout your day.
