2. Metric Conversions
Move the decimal to the right
Move the decimal to the left
Every metric unit is different from its neighbor by a factor of ten
When converting between two units the decimal point is moved the number of places equal to the distance between the two unit in the chart above and in the same direction of movement

3. Sample problem Convert the following Start with 53.
Move the decimal to the right
Move the decimal to the left
Convert the following
53 hg = ________dg
Start with 53.
Move the decimal 3 spaces to the right 53
Fill in the empty spaces with zeros dg

4. Sample Problem Start with 300.
Move the decimal to the right
Move the decimal to the left
Convert the following
300 cg = ________kg
Start with 300.
Move the decimal 5 spaces to the left
Fill in the empty spaces with zeros kg

5. More Practice Problems
