L EARNING O BJECTIVES Upon success completion of this lesson: 1.The student will understand the metric system units for volume, weight and length. 2.Be able to convert between each unit in each metric system. 3.Develop skills to convert within each metric system using a calculator. 4.Develop skills to convert within each metric system by moving the decimal.

M ETRIC S YSTEMS M EASURES V OLUME Liter(L or l) Milliliter(mL or ml) Cubic Centimeter(cc) *Note: A cubic centimeter (cc) is often used to denote a milliliter (mL or ml) Volume: Any form of liquids

When coming down each scale you multiple by ÷ by 1000 when going up × by 1000 when coming down

You will be moving the imaginary decimal to the right 3 times for each unit of measurement until you reach your destination gm mg mcg Sample Problem 5mcg= _______kg Move the decimal to the left when going up the scale Kg gm mg

S UMMARY ….. We learned how to memorize the units of measurements in the metric system by associating the letters with the alphabet and other symbolic images. We learned how to remember the conversion chart of the metric system. We learned how to move up and down the metric scale of each metric system of measurement using either a calculator or by moving the decimal.
