Title: THE METRIC SYSTEM


1
THE METRIC SYSTEM
  • PRESENTED BY MR. CONANT

2
WHY DO WE USE THE METRIC SYSTEM?
  • Almost all other countries are using the metric
    system
  • Other countries companies are refusing to buy
    products from the U.S. if not labeled in metric
    units
  • Scientists need a universal way to communicate
    data (SI Units)

3
APPROXIMATE CONVERSIONS BETWEEN METRIC US
LENGTH UNITS
  • A meter is about the same length as a yard
  • A meter is about three feet long
  • A decimeter is about four inches long
  • An inch is about 25 millimeters
  • A foot contains about 30 centimeters
  • A foot contains about 3 decimeters

4
WHAT DOES THE METRIC SYSTEM MEASURE?
  • The gram measures mass or how much something
    weighs
  • The liter measures volume which is used when
    measuring liquids
  • The meter measures the length of an object or
    the distance from place to place

5
THE METRIC CONVERSION CHART (STAIRCASE METHOD)
To convert to a smaller unit, move decimal point
to the right or multiply.
Kilo 1000 units
Hecto 100 units
Deka 10 units
Basic Unit
Deci 0.1 units
Centi 0.01 units
Milli 0.001 units
To convert to a larger unit, move decimal point
to the left or divide

TRY THIS USING THE STAIRCASE METHOD
1000 mg ______ g
Step 1 Determine if you are going to go up or
down the ladder. Step 2 Determine how many steps
there are from milligrams to
grams. Step 3 Move the decimal point the amount
of places that was determined in steps 1 2.
