Metric System I will be ale to measure to record data using a variety of SI units. Tuesday, March 04, 2014

3
What is the metric system? The first standardized system of measurement, based on the decimal was proposed in France about 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

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 hectodeca meter liter gram deci centimilli

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 = 100 centimeters or 1.00 meter = 100. centimeters kilo hectodeca meter liter gram deci centimilli

15
Metric System Now lets try our previous example from meters to kilometers: 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 hectodeca meter liter gram deci centimilli

16
Metric System Now lets start from centimeters and convert to kilometers centimeters = 4 kilometers centimeters = kilometers kilo hectodeca meter liter gram deci centimilli

17
Metric System Now lets start from meters and convert to kilometers 4000 meters = 4 kilometers kilo hectodeca meter liter gram deci centimilli kilo hectodeca meter liter gram deci centi milli Now lets start from centimeters and convert to meters 4000 centimeters = 40 meters

18
Metric System Now lets start from meters and convert to centimeters 5 meters = 500 centimeters kilo hectodeca meter liter gram deci centimilli kilo hectodeca meter liter gram deci centimilli Now lets start from kilometers and convert to meters 0.3 kilometers = 300 meters

19
Metric System Now lets start from kilometers and convert to millimeters 4 kilometers = millimeters or 4 kilometers = 40 hectometers = 400 decameters = 4000 meters = decimeters = centimeters = millimeters kilo hectodeca meter liter gram deci centimilli

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 hectodeca meter liter gram deci centimilli
