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

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

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

Sorry! That is not the BEST choice! Try again!

You're on a roll!!

Thumbs up!

You are first rate!!

Way to shine!

Awesome job!
