  4. What is a metric conversion? • Changing the same number to a different unit. Ex. 100cm = 1 m changes the number from centimeters to meters.

  5. If a swimming pool has 250,000 liters of water in it. How many kiloliters of water does it have in it? • 250,000 liters = ________________ kiloliters.

  6. How do you convert between metric units? • Change the prefix. • multiply or divide by powers of ten.
