### METRIC CONVERSION

Count Up to Six

King-Henry-Died-By-Drinking-Chocolate-Milk

• 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.

525,568 millimeters

Sometimes the number is too big for the unit being measured.

0.00654 km

Sometimes the number is too small for the unit being measured

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.

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.

• 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.
