The Metric System

1. The Metric System A simple way to measure

2. What is it??? A system of measurement based on multiples of 10 1 0 0 0 0.01 0.1 0.001

3. Each Multiple has its own name Milli = 0.001 or 1/1000 Centi = 0.01 or 1/100 Deci = 0.1 or 1/10 = 1 (no prefix) Deca = 10

4. Each Multiple has its own name Hecto = 100 Kilo = 1000

5. Length – “the Meter” • How long is something? • We use the Meter to measure the length of objects

6. The Meter Comes in Different Sizes Millimeter Centimeter Meter Kilometer 1 inch = 25.4 mm 1 inch = 2.54 cm 1 m = 3.28 ft 1 mile = 1.6 km

7. 10 Millimeters Is the same as 1 Centimeter 1mm 1mm 1mm 1mm 1mm 1mm 1mm 1mm 1mm 1mm

8. 100 Centimeters Is the same as 1 Meter

9. 1000 Millimeters Which is the same as 100 Centimeters Is the same as 1 Meter

10. 1000 Meters Is the same as 1 Kilometer

11. Need to Know!!!! • 10 mm = 1 cm • 100 cm = 1 m • 1000 m = 1 km • 1000 mm = 100 cm • 1000 mm = 1 m • How many mm = 1 km ???

12. The “Need to Know” on the previous slide holds true for EVERY unit of measurement in the metric system! You can substitute in gram for meter, or liter for gram… all three have the same exact conversions! • Keep this in mind as you continue through the presentation!

13. Mass – “the Gram” • Mass is a measure like weight, or how heavy something is. • Measurement like ounces and pounds.

14. The gram comes in different sizes too! Milligram gram kilogram 1 oz = 28.35 grams 1 pound = 2.2 kg

15. Volume – “the Liter” • Volume tells how much space an object takes up • Used to measure liquids • Measurement like cups, ounces and gallons

16. The Liter comes in different sizes like the meter and gram! Milliliter Liter Kiloliter 1 gallon = 3.78 liters 5 ml = 1 teaspoon = 1 cc
