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. We are going to use our knowledge about multiplying and dividing by 100 to convert centimetres to metres and to convert metres to centimetres.

4. There are 100 centimetres in 1 metre When we change from cm to m we divide by:- 100 Remember! When we divide by 100 the units move two places to the right. This is how we change 427cm into metres:- ÷100

5. There are 100 centimetres in 1 metre When we change from cm to m we divide by:- 100 Remember! When we divide by 100 the units move two places to the right. This is how we change 427cm into metres:- ÷100

15. Therefore:- 427cm = 4.27m cm m ÷100 ÷100 ÷100

16. Convert from centimetres to metres 354cm 15.4cm 779cm 52.4cm 939cm 395cm 25.8cm 3.54m 0.154m 7.79m 0.524m 9.39m 3.95m 0.258m ÷100

17. To change from metres to centimetres we MULTIPLY BY 100. REMEMBER When we multiply by 100 we move each digit two places to the left:- 3.51m =

18. To change from metres to centimetres we MULTIPLY BY 100. REMEMBER When we multiply by 100 we move each digit two places to the left:- 3.51m =

27. To change from metres to centimetres we MULTIPLY BY 100. REMEMBER When we multiply by 100 we move each digit two places to the left:- 3.51m = 351cm

28. Try changing these measurements in metres into centimetres 540cm 620cm 1270cm 300cm 760cm 54cm 30cm 5.4m 6.2m 12.7m 3m 7.6m 0.54m 0.3m x100
