Converting Units To convert from one unit to another is like following directions on a map. Which way? Left or Right?
Going Left??? When going from a smaller unit to a larger unit, you move Left on the map and the decimal moves to the LEFT .
Going Right??? When going from a larger unit to a smaller unit, you move RIGHT on the map and the decimal moves to the RIGHT .
Practice Time 4.5 m = ? cm
What to do first in the problem 4.5 m = __ cm ? Start at Meters and move to the Right to Centimeters. Decimal place moves to the RIGHT two spaces. . . . Kilo Hecto Deka Basic Unit Deci Centi Milli 4.5
As you move the decimal you will need to add zeros. . 4 . 5 0
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 ? Start at Liters and move to the Right to Millileters. Decimal place moves to the RIGHT three spaces. . . . . Kilo Hecto Deka Basic Unit Deci Centi Milli 6.6
Check your answer! 6.6 liters = 6,600 mL
