2. 2 Units of Measurement - Length ÷10÷100÷1000 mm cm m km x10x100x1000

3. 3 Units of Measurement - Length Examples 1. Convert 200m into cm. 200m = 200 x 100= 20 000 cm 2. Convert 5100m into km. 5100m = 5100 ÷ 1000 = 5.1 km

4. 4 Units of Measurement - Mass ÷1000 mg g kg x1000 ÷1000 tonne x1000

5. 5 Units of Measurement - Mass Examples 1. Convert 2kg into g. 2kg = 2 x 1000= 2 000 g 2. Convert 7800kg into tonne. 7800kg = 7800 ÷ 1000 = 7.8 tonne

6. 6 Units of Measurement - Capacity ÷1000 mL L kL ML x1000

7. 7 Units of Measurement - Capacity Examples 1. Convert 3.2 L into mL. 3.2 L = 3.2 x 1000= 3200 mL 2. Convert 6700mL into L. 6700mL =6700 ÷ 1000= 6.7 L
