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? MeterLengthLiterVolumeGramWeight 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 thedoorknob.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 centimetersThe 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 teaspoonWhen you think of 2 kiloliters (kL) think of:A hot tubHow 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 clipWhen you think of a kilogram (kg) think of:A little more than 2 pounds.
11 Measurement Conversions to Know: 1 m = 100 cm1 cm = 10 mm1 m = 1,000 mm1 km = 1,000 m1 g = 100 cg1 cg = 10 mg1 g = 1,000 mg1 kg = 1,000 g1 L = 100 cL1 cL = 10 mL1 L = 1,000 mL1 kL = 1,000 mL

13 Metric SystemIf you move to the left in the diagram, move the decimal to the leftIf you move to the right in the diagram, move the decimal to the rightkilohectodecameterlitergramdecicentimilli
14 Metric SystemAn easy way to move within the metric system is by moving the decimal point one place for each “step” desiredExample: change meters to centimeters1 meter = centimetersor1.00 meter = centimeterskilohectodecameterlitergramdecicentimilli
15 Metric SystemNow let’s try our previous example from meters to kilometers:16093 meters = kilometersSo 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)kilohectodecameterlitergramdecicentimilli
16 Metric SystemNow let’s start from centimeters and convert to kilometerscentimeters = 4 kilometerscentimeters = kilometerskilohectodecameterlitergramdecicentimilli
17 Metric System Now let’s start from meters and convert to kilometers 4000 meters = 4 kilometerskilohectodecameterlitergramdecicentimilliNow let’s start from centimeters and convert to meters4000 centimeters = 40 meterskilohectodecameterlitergramdecicentimilli
18 Metric System Now let’s start from meters and convert to centimeters 5 meters = 500 centimeterskilohectodecameterlitergramdecicentimilliNow let’s start from kilometers and convert to meters0.3 kilometers = 300 meterskilohectodecameterlitergramdecicentimilli
19 Metric SystemNow let’s start from kilometers and convert to millimeters4 kilometers = millimetersor4 kilometers = 40 hectometers = 400 decameters= 4000 meters = decimeters= centimeters = millimeterskilohectodecameterlitergramdecicentimilli
20 Metric SystemSummaryBase units in the metric system are meter, liter, gramMetric system is based on powers of 10For conversions within the metric system, each “step” is 1 decimal place to the right or leftUsing the diagram below, converting to the right, moves the decimal to the right and vice versakilohectodecameterlitergramdecicentimilli
