2. We use different metric units to measure :-
Distance
Capacity
Weight
We can use our knowledge of multiplying and dividing by 10, 100 or 1000 to change or convert measurements in one unit to measurements in another unit.

3. CONVERTING DECIMALS THINGS TO REMEMBER:
Multiply -- (the number gets larger)
Divide -- (the number gets smaller)
kilo- hecto- deka- meter . deci- centi- milli-
gram
Liter
Remember this mnemonic device to help you remember the order of the metric prefixes:

4. We are going to use our knowledge about multiplying and dividing by 100 to convert centimeters to meters and to convert meters to centimeters.
