**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: Kangaroos Hop Down Mountains Drinking Chocolate Milk

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.

**4 2 7 ÷100 100 Remember! This is how we change 427cm into meters:- H T**

There are 100 centimeters in 1 meter When we change from cm to m we divide by:- 100 Remember! When we divide by 100 we move the decimal two places to the left (the units move two places to the right). This is how we change 427cm into meters:- H T O th hth 4 2 7 ÷100
