1. The Metric System
A simple way to measure

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

3. Each Multiple has its own name
Milli = 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
A meter is almost equal to a yard in the English System
* 1 yard= meter, 1 m = 3.28 feet, 1 yard = 3 feet

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 1 Centimeter Is the same as 1mm 1mm 1mm 1mm 1mm 1mm 1mm

8. 100 Centimeters
Is the same as
1 Meter

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

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
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.
The gram is closest to an ounce in the English System of measurement

14. The gram comes in different sizes too!
Milligram
gram
kilogram
1 oz = 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
The liter is closest to a quart in the English System of measurement
(1 liter = quarts, 1 quart = 4 cups)

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
