2. What is the metric system?
The first standardized system of measurement, based on the decimal was proposed in France about 1670.
However, it was not until 1791 that such a system was developed.
It was called the "metric" system, based on the French word for measure.
At that time, every country had their own system of weights and measures. England had three different systems just within its own borders!!
On May 20, 1875, delegates of 17 countries signed the Meter Convention. It was amended in 1921 and today 48 countries use it.

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

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. How to convert within the metric system:
Example 1: to convert 3 meters into decimeters, multiply 3 by 10 one time.
3 m = 3* 10 dm = 30 dm
Example 2: to convert 7 hectoliters into milliliters, multiply 7 by 10 five times.
7 hL = 7 * 10 * 10 * 10 * 10 * 10 mL = 700,000 mL

14. Now you try: 7 km = __________ m 6 g = __________ cg
9.15 kL = __________ L
6.25 kg = __________ mg
14.2 m = __________ cm

15. How to convert within the metric system:
Example 3: to convert 6 grams into kilograms, divide 6 by 10 three times.
6 g = 6 ÷ 10 ÷ 10 ÷ 10 kg = kg
Example 2: to convert 17 millimeters into centimeters, divide 17 by 10 one time.
17 mm = 17 ÷ 10 cm = 1.7 cm

16. Now you try: 14 mL = __________ L 3.97 g = __________ kg
915 L = __________ kL
45 mg = __________ dag
10 m = __________ dam

17. 13 kg = ________ g
0.013

18. 240 mL = _______ L
240,000
2.4 8
