The Metric System

• The metric system is a measurement system based on our decimal (base 10) number system.

• Other countries and all scientists and engineers use the metric system for measurement.

Metric Prefixes• Metric Units• The metric system has prefix modifiers that are multiples of

10.

Page 5: Meters, Grams and Liters

Meters

• Meters measure length or distance

• One millimeter is about the thickness of a dime.

Page 6: Meters, Grams and Liters

Meters• One centimeter is

about the width of a large paper clip

•or your fingernail.

Page 7: Meters, Grams and Liters

Meters

• A meter is about the width of a doorway

Page 8: Meters, Grams and Liters

Meters

• A kilometer is about six city blocks or 10 football fields.

• 1.6 kilometers is about 1 mile

Page 9: Meters, Grams and Liters

Gram

• Grams are used to measure mass or the weight of an object.

Page 10: Meters, Grams and Liters

Grams

• A milligram weighs about as much as a grain of salt.

Page 11: Meters, Grams and Liters

Grams

• 1 gram weighs about as much as a small paper clip.

• 1 kilogram weighs about as much as 6 apples or 2 pounds.

Page 12: Meters, Grams and Liters

Liters

• Liters measure liquids or capacity.

Page 13: Meters, Grams and Liters

Liter

• 1 milliliter is about the amount of one drop

Page 14: Meters, Grams and Liters

Liter

• 1 liter is half of a 2 liter bottle of Coke or other soda

Page 15: Meters, Grams and Liters

Liter

• A kiloliter would be about 500 2-liter bottles of pop

Changing Metric Units

• To change from one unit to another in the metric system you simply multiply or divide by a power of 10.

Page 31: Meters, Grams and Liters

To change from a larger unit to a smaller unit, you need to multiply.

1 km x 1000 = 1000 m

1 m x 100 = 100 cm

1 cm x 10 = 10mm

To change from smaller units to larger units you divide by a

power of ten.

1000mm ÷ 10 = 100cm

100cm ÷ 10 = 10dm

10dm ÷ 10 = 1m
