To convert from one u n it to another is like following directions on a map. Converting Units Which way? Left or Right?

When going from a smaller unit to a larger unit, you move Left on the map and the decimal moves to the LEFT. However, the actual number decreases. Going Left???

When going from a larger unit to a smaller unit, you move RIGHT on the map and the decimal moves to the RIGHT. However, the actual number increases. Going Right???

Let’s take a look!!!

Practice Time 4.5 m = ? cm

What to do first in the problem 4.5 m = __ cm ? Basic UnitDeciCenti Milli DekaHectoKilo Start at Meters and move to the Right to Centimeters. Decimal place moves to the RIGHT two spaces

As you move the decimal you will need to add zeros

Is this your Final Answer? 4.5 m = 450 cm

Let’s do another one! 6.6 liters = _____ mL

What to do first in the problem 6.6 L = __ mL ? Basic UnitDeciCentiMilliDekaHectoKilo Start at Liters and move to the Right to Millileters. Decimal place moves to the RIGHT three spaces

Check your answer! 6.6 liters = 6,600 mL

Let’s Go the Other Way! 3,580 mm = _______ m?

Let’s move to the left this time. 3,580mm = ___________m? Basic UnitDeciCentiMilliDekaHectoKilo Start at Millimeters and move to the Left to Meters. Decimal place moves to the LEFT three spaces

Check your answer: 3,580mm = 3.58m

Quiz Time cm = ? mm cm = ? m g = ? mg g = ? kg 5. 2L = ? mL

How did We do?? cm =280 mm cm = g = g = 5. 2 L = 4.38 m 72,000 mg kg 2,000 mL

Yeah!!! We Are Done
