3 We use different metric units to measure :- 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.

4 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

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

6 There are 100 centimeters in 1 meter When we change from cm to m we divide by:- Remember! When we divide by 100 we move the decimal two places to the left (the units move two places to the right). HTOthhthth ÷100 This is how we change 427cm into meters:-

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