3. What is the metric system?
The first standardized system of measurement, based on the decimal was proposed in France about 1670.
It was created to develop a unified, natural, universal system of measurement.
In 1790 King Louis XVI of France assigned a group to begin this task.
At that time, every country had their own system of weights and measures. England had three different systems just within its own borders!!
It was called the "metric" system, based on the French word for measure.
As of 2005, only three countries, the United States, Liberia, and Myanmar, have not changed over to the metric system.
The official modern name of the metric system is the International System of Units or abbreviated SI.

4. What are the metric measurements that we are learning about?
Meter
Length
Liter
Volume
Gram
Weight or Mass

5. How to remember different lengths in the metric system:
When you think of a millimeter (mm)
think of:
The thickness of a dime.
When you think of a centimeter (cm) think of:
The width of your pinky.

6. How to remember different lengths in the metric system:
When you think of a meter (m)
think of: The height of the
doorknob.
When you think of a kilometer (km) think of:
A little more than half of a mile

7. How to understand the ruler:
One side has inches (duh!)
The other side is the metric side.
The big numbers represent centimeters
The smaller lines represent millimeters.
How many millimeters are in a centimeter? 10

8. With the group you will be put into, use a meter stick to measure the items on your chart.
Be sure to measure in meters, centimeters, and millimeters.

9. How to remember different volumes in the metric system:
When you think of a liter (L) think of:
About the size of a bottle of water.
When you think of 5 milliliters (mL) think of:
One teaspoon
When you think of 2 kiloliters (kL) think of:
A hot tub
How to remember different volumes in the metric system:

10. How to remember different masses in the metric system:
When you think of a gram (g) think of:
A paper clip
When you think of a kilogram (kg) think of:
A little more than 2 pounds.

11. Measurement Conversions to Know:
1 m = 100 cm
1 cm = 10 mm
1 m = 1,000 mm
1 km = 1,000 m
1 g = 100 cg
1 cg = 10 mg
1 g = 1,000 mg
1 kg = 1,000 g
1 L = 100 cL
1 cL = 10 mL
1 L = 1,000 mL
1 kL = 1,000 mL

12. What is the order of the metric system?
King Henry Died by Drinking Chocolate Milk
King: Kilo
Henry: Hecto
Died: Deca
By: Base (m, L, g)
Drinking: Deci
Chocolate: Centi
Milk: Milli

13. Metric System
If you move to the left in the diagram, move the decimal to the left
If you move to the right in the diagram, move the decimal to the right
kilo
hecto
deca
meter
liter
gram
deci
centi
milli

14. Metric System
An easy way to move within the metric system is by moving the decimal point one place for each “step” desired
Example: change meters to centimeters
1 meter = centimeters or
1.00 meter = centimeters
kilo
hecto
deca
meter
liter
gram
deci
centi
milli

15. Metric System
Now let’s try our previous example from meters to kilometers:
16093 meters = kilometers
So for every “step” from the base unit to kilo, we moved the decimal 1 place to the left (the same direction as in the diagram below)
kilo
hecto
deca
meter
liter
gram
deci
centi
milli

16. Metric System
Now let’s start from centimeters and convert to kilometers
centimeters = 4 kilometers
centimeters = kilometers
kilo
hecto
deca
meter
liter
gram
deci
centi
milli

17. Metric System Now let’s start from meters and convert to kilometers
4000 meters = 4 kilometers
kilo
hecto
deca
meter
liter
gram
deci
centi
milli
Now let’s start from centimeters and convert to meters
4000 centimeters = 40 meters
kilo
hecto
deca
meter
liter
gram
deci
centi
milli

18. Metric System Now let’s start from meters and convert to centimeters
5 meters = 500 centimeters
kilo
hecto
deca
meter
liter
gram
deci
centi
milli
Now let’s start from kilometers and convert to meters
0.3 kilometers = 300 meters
kilo
hecto
deca
meter
liter
gram
deci
centi
milli

19. Metric System
Now let’s start from kilometers and convert to millimeters
4 kilometers = millimeters or
4 kilometers = 40 hectometers = 400 decameters
= 4000 meters = decimeters
= centimeters = millimeters
kilo
hecto
deca
meter
liter
gram
deci
centi
milli

20. Metric System
Summary
Base units in the metric system are meter, liter, gram
Metric system is based on powers of 10
For conversions within the metric system, each “step” is 1 decimal place to the right or left
Using the diagram below, converting to the right, moves the decimal to the right and vice versa
kilo
hecto
deca
meter
liter
gram
deci
centi
milli
