8. Converting within the Metric System
Refer to the chart on the hand out.
When moving up the step – divide OR move the decimal to the left
When moving down the step – multiply OR move the decimal to the right
Convert the following:
560 mm to metres m
mL to litres 34 L
mg to kilograms 78kg
5km to centimetres cm
50L to millilitres mL
kg to milligrams 50 mg
