The Metric System

Meters, Grams and Liters


The metric system
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 Prefixes

  • Metric Units

  • The metric system has prefix modifiers that are multiples of 10.



Meters
Meters

  • Meters measure length or distance

  • One millimeter is about the thickness of a dime.


Meters1
Meters

  • One centimeter is about the width of a large paper clip

  • or your fingernail.


Meters2
Meters

  • A meter is about the width of a doorway


Meters3
Meters

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

  • 1.6 kilometers is about 1 mile


Gram

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


Grams
Grams

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


Grams1
Grams

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

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


Liters
Liters

  • Liters measure liquids or capacity.

2 Liter Soda


Liter
Liter

  • 1 milliliter is about the amount of one drop


Liter1
Liter

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



What unit would you

use to measure each of

the following items?















Changing metric units
Changing Metric Units bracelet?

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


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

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


Place values of metric prefixes1
Place Values of Metric Prefixes multiply.

Movethe decimal point to the right to multiply.



To change from smaller units to larger units you divide by a power of ten

To change from smaller units to larger units you divide by a power of ten.

1000mm ÷ 10 = 100cm

100cm ÷ 10 = 10dm

10dm ÷ 10 = 1m


Place values of metric prefixes3
Place Values of Metric Prefixes power of ten.

Movethe decimal point to the left to divide.



Sorry
Sorry! power of ten.

  • That is not the BEST choice!

Try again!


You're on a roll!! power of ten.


Thumbs up! power of ten.


You are first rate!! power of ten.


Way to shine! power of ten.


Awesome job! power of ten.
