CONVERTING UP AND DOWN WITHIN EACH METRIC SYSTEM

CONVERTING UP AND DOWN WITHIN EACH METRIC SYSTEM USING A CALCULATOR OR MOVING THE DECIMAL

LEARNING OBJECTIVES 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.

METRIC SYSTEMS MEASURES VOLUME Liter (L or l) Milliliter (m. L or ml) Cubic Centimeter (cc) *Note: A cubic centimeter (cc) is often used to denote a milliliter (m. L or ml) Volume: Any form of liquids

METRIC SYSTEM MEASURES WEIGHT Kilograms Grams Milligrams Micrograms (Kg) (g or gm) (mg) (mcg) Note: Weight is a solid

METRIC SYSTEM MEASURES LENGTH Meter Centimeter (cm) Millimeter (m) (mm) Note: Length is a measure of distance

USING THE CONVERSION CHART AND YOUR CALCULATOR Volume L m. L ÷ by 1000 when going up Weight kg gm mg mcg Length m cm mm × by 1000 when coming down Note: There are 1000 units between each metric measurement When moving up each scale, you divide by 1000 on your calculator. When coming down each scale you multiple by 1000.

CONVERTING WITHIN EACH METRIC SYSTEM BY MOVING THE DECIMAL Sample Problem: 5 kg = _______ mcg *note: 5. 0 (imaginary decimal is always at the end of each whole number) Using the metric scale, you are going down units from kilograms to micrograms. You will be moving the imaginary decimal to the right 3 times for each unit of measurement until you reach your destination. 5. 000 000 gm mg mcg Sample Problem 5 mcg= _______kg Move the decimal to the left when going up the scale 0 000 005 Kg gm mg

LET’S TRY IT ON OUR OWN NOW 25 mcg= ______mg • answer = 0. 025 mg 100 mg=_______g • answer = 0. 1 g 15. 6 L = ______m. L • answer = 15, 600 m. L 566. 32 m. L = _____L • answer = 0. 56632 L 1 m = _____mm • answer = 1000 mm

SUMMARY…. . 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.
