21. Changing Metric Units
To change from one unit to another in the metric system you simply multiply or divide by a power of 10.

22. To change from a larger unit to a smaller unit, you need to multiply.
1 km x 1000 = 1000 m
1 m x 100 = 100 cm
1 cm x 10 = 10mm

23. To change from smaller units to larger units you divide by a power of ten.
1000mm ÷ 10 = 100cm
100cm ÷ 10 = 10dm
10dm ÷ 10 = 1m
