2
What are Metric Conversions?

• Sometimes we need to change from one measurement
  to another.
• This is usually done because the unit that is
  used is either too big or too small for that type
  of measurement.

3
TOO BIG !!!

• 525,568 millimeters
• Sometimes the number is too big for the unit
  being measured.

4
Too Small

• 0.00654 km
• Sometimes the number is too small for the unit
  being measured

5
How Do We Fix This Problem?

• We can correct these problems by doing a
  process called Metric Conversion. When you do a
  Metric Conversion, you are changing from one unit
  of measurement to another.

6
So How Do I Do A Metric Conversion?

• We will be using a method called The Stair-step
  Method of Metric Conversion.
• It requires you to move the decimal in the number.

• -The first letter of the prefix in the unit of
  measurement tells you which step to start on.
• -The first letter in the second unit of
  measurement tells you which step to stop on.
• -Find which step to start on, and count the
  number of steps it takes to get to the step that
  you need to stop on.

How Do I Use This (cont.)?

• If you went to the right(downstairs) the
  decimal in the first measurement moves that many
  places to the right.
• If you went to the left (upstairs) then the
  decimal moves to the left. Fill any empty places
  with zeros.
